If an image is added to a site via the rich text field, do we have a way to apply a custom wrapper or mini template to it? IE I want to apply some markup srcset to some user added images. I can only seem to achieve this when the image markup is in the template itself. https://github.com/rolandtoth/MarkupSrcSet/wiki I can probably achieve this with RepeaterMatrix and by creating a specific Images field (and images template) but outside of that ? Thanks

Continuing my journey into PW hooks, I'm trying to find a way to retrieve all images from a page that explicitly *do not* have a certain tag (or tags) attached to them. Found this post from 2015 But I'm wondering if there's a more elegant way to go about this. Let's say I have a multi-image field called "images_header" and instead of $page->images_header->findTag('mytag'); I would like to do this: $page->images_header->excludeTag('mytag'); So I'd be able to do // find images that don't have the tag "mytag" $images = $page->images_header->excludeTag('mytag'); // check if there's any images if (count($images)>0) { // do something.. } Would this be possible by hooking into Pagefiles somehow? There's this bit in /wire/core/Pagefiles.php Line 626 that I'd basically just need to reverse (or at least in my mind ? ) public function findTag($tag) { $items = $this->makeNew(); foreach($this as $pagefile) { if($pagefile->hasTag($tag)) $items->add($pagefile); } return $items; } Any ideas on how this could be done in a graceful manner? Thanks in advance!

Hello Dear PW Gurus. Hope you fair well in these Corona Crisis times. Anyhow, i have a problem with a Cryptic error message that shows up when i am trying to Delete images out of a Images field. The Error message does say a little but it does not make sense to me why i can´t delete the images because of it. Is it some permission issue perhaps? I will attach screenshots of it and what i did prior to it. I am from sweden so ignore the funny words here and there. Hope you all can send me on the right track. i am running PW 3.0.139 on this install. Step1: Step 2: Select the images with the trashcan symbol Step 3: Cryptic Error message I am scratching my head on this one, have not seen this before. Thankfull for all help. /EyeDentify

This short script loops through some images from an XML feed and pushes new ones to an image field. It all works perfectly, except for some reason the last image (only) in the loop each time doesn't receive the image description... can everyone spot why? TIA! ? foreach ($propertyImages as $img) { $fileName = trim($img[0]); if ( !empty($fileName) ) { $imgPath = '../property_data/'.$fileName; if(file_exists($imgPath) && !in_array(strtolower($fileName),$currentImages)) { $p->property_images->add($imgPath); $p->save(); $newImg = $p->property_images->last(); $newImg->description = $img[1]; $p->save(); } } }

Hi. I've been using Processwire for a few years now and installed it on a few different shared hosting servers without issues, but I'm now running into an issue on a Fasthosts shared server that I've not seen before. The installation goes ok and I have a working default site profile but I am unable to complete any uploads of images. It just hangs at the progress spinner during the upload. I thought it might be a priviledge issue so have temporarily set the dir / file privs. as 777 / 666 just to test that but it made no difference. I have no errors in the wire log. In server error log I have: set_time_limit() has been disabled for security reasons in ....htdocs/wire/core/ImageSizerEngine.php on line 1035 and i note in the assets/file dir. where the image is being stored the date on the file being created has a year of 1970 and 0 length. If I leave the page this file disappears and nothing has been stored. Does anyone know how I can enable set_time_limit if this is likely to be the problem? Many thanks! Paul

EDIT: all development and discussion of this module has been moved to Module FieldtypeImagePicker which now contains all features of this module and more. This module will not be maintained any further. The information below remains for pure historical reasons. I am happy to present my new fieldtype FieldtypeImageFromPage. It is made up of 2 modules: Fieldtype Image Reference From Another Page is a Fieldtype that stores a reference to a single image from another page. The image can be selected with the associated Inputfield. Inputfield Select Image From Page is an Inputfield to select a single image from images on a predefined page and it's children. And there also is a helper module that takes care of cleanup tasks. This module evolved out of a discussion about my other Module FieldtypeImagePicker. It caters for use cases where a set of images is being reused multiple times across a site. With this fieldtype these images can be administered through a chosen page. All images uploaded to that page will be available in the inputfield. When to use ? Let editors choose an image from a set of images that is being used site-wide. Ideal for images that are being re-used across the site. Suited for images that are used on multiple pages throughout the site (e.g. icons). Other than the native ProcessWire images field, the images here are not stored per page. Only references to images on another page are stored. This has several advantages: one central place to organize images when images change, you only have to update them in one place. All references will be updated, too. (Provided the name of the image that has changed stays the same) Features Images can be manipulated like native ProcessWire images (resizing, cropping etc.) Image names are fully searchable through the API Accidental image deletion is prevented. When you want to delete an image from one of the pages that hold your site-wide images, the module searches all pages that use that image. If any page contains a reference to the image you are trying to delete, deletion will be prevented. You will get an error message to help you edit those pages and remove references there before you can finally delete the image. How to install and setup Download and install this module like any other modules in ProcessWire Create a page in the page tree that will hold your images. This page's template must have an images field Upload some images to the page you created in step 2 Create a new field. As type choose 'Image Reference From Another Page'. Save the field. In 'Details' Tab of the field choose the page you created in step 2 Click Save button Choose the images field name for the field that holds your images (on page template from step 2) Click Save button again Choose whether you want to include child pages of page from step 2 to supply images Add the field to any template You are now ready to use the field View of the inputfield on the page edit screen: View of the field settings The module can be installed from this github repo. Some more info in the README there, too. In my tests it was fairly stable. After receiving your valued feedback, I will eventually add it to the modules directory. My ideas for further improvement: - add ajax loading of thumbnails Happy to hear your feedback!

Hi, Have been working with ProcessWire for a few months now, successfully implementing several sites. I am compiling data management into modules for our clients. Several sites are using those modules now. The modules are using RockMigrations to install fileds, templates and pages. Today, I installed a new site. And now I am tripping over an issue that I cannot explain. Content on pages is organized in 'rows'. The users can add row by using RepeaterMatrix...then completing the fields to add data to the row. One particular content row has image fields. When I upload the images to the fields, all works as expected. The images appear in the RepeaterMatrix and I do find the images in assets/files/xxxx. But the images are not displayed in the front-end (see attachment). As you can see in the attachment, the various text and textarea fields in the RepeaterMatrix item are displayed correctly. I have done the following: Compare field settings to the existing implementations: they are identical Compare the RepeateMatrix settings and permissions to existing implementations: they are identical Change field name. No change. Delete field and created manually (including once with different name). No change. If I dump the element with Tracey, I get the following output: If Max Number = 1 null If Max Number = 0 count => 0 page => "/processwire/repeaters/for-field-136/for-page-1/1574873590-62-1/" (60) field => "wk_inhalt_start_links_bild" (26) url => "/serverpath/site/assets/files/1046/" (30) path => "/serverpath/serverpath/serverpath/serverpath/site/assets/files/1046/" (56) items => array () I would venture that there is an issue regarding images on the shared server...but another content element on the site works just fine with images. Bit stumped right now. Especially considering that I made the same installation earlier today on a different server successfully. I would appreciate any ideas on where to investigate this issue.

Hello all, sharing my new module FieldtypeImageReference. It provides a configurable input field for choosing any type of image from selectable sources. Sources can be: a predefined folder in site/templates/ and/or a page (and optionally its children) and/or the page being edited and/or any page on the site CAUTION: this module is under development and not quite yet in a production-ready state. So please test it carefully. UPDATE: the new version v2.0.0 introduces a breaking change due to renaming the module. If you have an older version already installed, you need to uninstall it and install the latest master version. Module and full description can be found on github https://github.com/gebeer/FieldtypeImageReference Install from URL: https://github.com/gebeer/FieldtypeImageReference/archive/master.zip Read on for features and use cases. Features Images can be loaded from a folder inside site/templates/ or site/assets Images in that folder can be uploaded and deleted from within the inputfield Images can be loaded from other pages defined in the field settings Images can be organized into categories. Child pages of the main 'image source page' serve as categories mages can be loaded from any page on the site From the API side, images can be manipulated like native ProcessWire images (resizing, cropping etc.), even the images from a folder Image thumbnails are loaded into inputfield by ajax on demand Source images on other pages can be edited from within this field. Markup of SVG images can be rendered inline with `echo $image->svgcontent` Image names are fully searchable through the API $pages->find('fieldname.filename=xyz.png'); $pages->find('fieldname.filename%=xy.png'); Accidental image deletion is prevented. When you want to delete an image from one of the pages that hold your site-wide images, the module searches all pages that use that image. If any page contains a reference to the image you are trying to delete, deletion will be prevented. You will get an error message with links to help you edit those pages and remove references there before you can finally delete the image. This field type can be used with marcrura's Settings Factory module to store images on settings pages, which was not possible with other image field types When to use ? If you want to let editors choose an image from a set of images that is being used site-wide. Ideal for images that are being re-used across the site (e.g. icons, but not limited to that). Other than the native ProcessWire images field, the images here are not stored per page. Only references to images that live on other pages or inside a folder are stored. This has several advantages: one central place to organize images when images change, you only have to update them in one place. All references will be updated, too. (Provided the name of the image that has changed stays the same) Installation and setup instructions can be found on github. Here's how the input field looks like in the page editor: If you like to give it a try, I'm happy to hear your comments or suggestions for improvement. Install from URL: https://github.com/gebeer/FieldtypeImageReference/archive/master.zip Eventually this will go in the module directory, too. But it needs some more testing before I submit it. So I'd really appreciate your assistance. Thanks to all who contributed their feedback and suggestions which made this module what it is now.

Hello everybody, I'm hosting a Processwire Installation for a client. It runs on Processwire 2.5.3. Over the years everything was fine but now there is an issue with one Image-Field in one Template. Trying to upload an Image the Error "Not enough Memory to load/resize" occure. Other Image-Fields in all other Templates working without any issue. The Images I Tried to upload are very small (600px * 420px). The Images blongs to a News feed, and worked before. I read about the problem in the forum but I can't get this solved. I have no access to the php.ini to modify the memory_limit. I tried to update the Processwire Verion but failed. (Tried 2.7 /2.8 / 3.2) Got Always Internal Server Error and in the error Log: Compile Error: Cannot redeclare PageEditFieldPermissionConfig()…. Has anybody any idea how I can get this solved? Thank you so much Martin

Hi again, after trying pages2PDF, RockPDF and mpdf I'm not sure which of them I should use. Of course, there is also wirePDF. I merged mpdf with rockPDF, add a footer and a page in Landscape and that works, like in the code-snippet below but be am I on the right way? After that I tried a couple of times rendering an image. Nothing happend, the same with Pages2PDF too. I also copied an Image-URL within processwire and tried further getting an Image within the PDF-Document, but it still display only the red marked placeholder. I simply would like create an PDF on click from some Pages including the Images. Are there special requirements on Debian 10 with Apache and php 7.3 using Processwire 3.0.123.? Is there a guide that I didn't found? Is somebody out there who has a similar issue solved and would you be so kind to explain? $pdf = $modules->get('RockPdf'); $mpdf = $pdf->mpdf; # $mpdf->showImageErrors = true; $pdf->set('SetHeader', 'header text'); $mpdf->AddPage('L'); # $mpdf->Image(urlencode('site/assets/files/1845/image-2.275x200.jpg'), 0, 0, 210, 297, 'jpg', '', true, false); $pdf->set('SetFooter', ' <table width="100%"> <tr> <td width="33%">{DATE j.m.Y}</td> <td width="33%" align="center">{PAGENO}/{nbpg}</td> <td width="33%" style="text-align: right;">whatever</td> </tr> </table>'); $pdf->show(); // generate pdf

Hello community, we have a website running version 3.0.118. The owner would like to have a watermark merged to the images, that are being uploaded in the CKEditor as a requirement. Image upload besides the CKEditor within galleries and single images works as a charm already. We also use croppable image 3 there. (PIM2) To realize this requirement, I thought of using a hook in the admin area. So, I read a lot in our forums and tested this by adding a hook into the ready.php file. $this->addHookAfter('InputfieldFile::fileAdded',function(HookEvent$event){ wire('log')->save('test','Image upload works'); ... The log entry is being created correctly. But when I try to use the pim/watermark-function like in a template, he cannot find the watermark-image anymore. Furthermore, when I try to get the page-id, it does not seem to be accessible, because the application does not seem to know how to reference it, or I dont know the right way to do so… So my questions are: Is this the right attempt at all or will there be another, better workaround? It seems, I cannot access the page object (of the content page) within this scope or file but I would need it to save the processed image inside the right files/id folder Would it be better to place the hook into the admin-template? (or admin.php) Thanks for any hints in advance. ?

Hi, I'm facing a strang problem. In my template I'm setting different sizes for srcset: $view->set('images', $page->picture); <img srcset="{$img->size(780,0)->url} 780w, {$img->size(1024,0)->url} 1024w, {$img->size(1440,0)->url} 1440w" src="{$img->url}" class="col__image"> All fine. However, the moment I reorder images in backend the different generated image sizes are broken. Does somebody has an idea what could cause it? Version: ProcessWire 3.0.123 Thanks! Toni

Hello I'm working on a project that use PW as backend CMS. PW serves formatted data of each page but the engine simply generates json from pagearray. I would like to set one or more variations on images, so I think it would be useful if there were a field to set possible variations... even with overrides!

Can I convert uploaded images to PNG, GIF, BMP -> JPEG? Is there any function in the API that I can change the file type?

Repeater Images Adds options to modify Repeater fields to make them convenient for "page-per-image" usage. Using a page-per-image approach allows for additional fields to be associated with each image, to record things such as photographer, date, license, links, etc. When Repeater Images is enabled for a Repeater field the module changes the appearance of the Repeater inputfield to be similar (but not identical) to an Images field. The collapsed view shows a thumbnail for each Repeater item, and items can be expanded for field editing. Screencast Installation Install the Repeater Images module. Setup Create an image field to use in the Repeater field. Recommended settings for the image field are "Maximum files allowed" set to 1 and "Formatted value" set to "Single item (null if empty)". Create a Repeater field. Add the image field to the Repeater. If you want additional fields in the Repeater create and add these also. Repeater Images configuration Tick the "Activate Repeater Images for this Repeater field" checkbox. In the "Image field within Repeater" dropdown select the single image field. You must save the Repeater field settings to see any newly added Image fields in the dropdown. Adjust the image thumbnail height if you want (unlike the core Images field there is no slider to change thumbnail height within Page Edit). Note: the depth option for Repeater fields is not compatible with the Repeater Images module. Image uploads feature There is a checkbox to activate image uploads. This feature allows users to quickly and easily add images to the Repeater Images field by uploading them to an adjacent "upload" field. To use this feature you must add the image field selected in the Repeater Images config to the template of the page containing the Repeater Images field - immediately above or below the Repeater Images field would be a good position. It's recommended to set the label for this field in template context to "Upload images" or similar, and set the visibility of the field to "Closed" so that it takes up less room when it's not being used. Note that when you drag images to a closed Images field it will automatically open. You don't need to worry about the "Maximum files allowed" setting because the Repeater Images module overrides this for the upload field. New Repeater items will be created from the images uploaded to the upload field when the page is saved. The user can add descriptions and tags to the images while they are still in the upload field and these will be retained in the Repeater items. Images are automatically deleted from the upload field when the page is saved. Tips The "Use accordion mode?" option in the Repeater field settings is useful for keeping the inputfield compact, with only one image item open for editing at a time. The "Repeater item labels" setting determines what is shown in the thumbnail overlay on hover. Example for an image field named "image": {image.basename} ({image.width}x{image.height}) https://github.com/Toutouwai/RepeaterImages https://modules.processwire.com/modules/repeater-images/

In the RTE, when inserting a link, there are several input fields that can be used to select a page, including a text input field that will auto-complete with pages on the site. When inserting an image, there is only an option to navigate the page tree. (equivalent to the second input option 'Select Page...' on the Insert Link screen from the RTE. When inserting an image from another page buried somewhere in the page tree, if you know the name of the page, it would often be quicker to use an auto-complete text field than 'Select Page...' option. It would be nice if the image insertion dialog offered the same functionality as the link insertion dialog so that when selecting a page it's possible to choose either to navigate the page tree, or have a text auto-complete field.

I just wanted to share that I added an AJAX-powered gallery to an artist website that I developed and host: https://jackpinecreations.com/gallery/ There were two things that frustrated me about creating this. Perhaps you can show me a better way. 1. After creating my processing script, which I placed under /templates/scripts/get-items.php, I realized that I would get a 403, due to ProcessWire's routing and security. This forced me to have to create a template and page for this little script. This was frustrating simply because it seemed unnecessarily confusing. But worse, see #2. 2. I usually use config.php to prepend and append each of my templates with a head.inc and foot.inc, which keeps my templates easy to use and I don't have to go and use the GUI to do so on each template separately. However, since I realized I needed to create a new template and page so as to access it, whenever I sent POST params to it, I would get the header and footer along with it!!! I could find no workarounds and had to remove the pre/append calls in config.php and use the GUI on each template individually. Code Below if you're interested: HTML and JavaScript (forgive my sad JavaScript skills, I know this can be tightened up) <!-- Begin Grid --> <div class="container mt-4"> <div id="gallery" class="row"> <?php foreach ($page->children("limit=9") as $child): ?> <div class="col-6 col-md-4 gallery-item"> <a href="<?= $child->url ?>" title="View <?= $child->title ?>"> <img class="gallery-item" src="<?= $child->item_featured_image->size(640, 640)->url ?>" alt="<?= $child->title ?> Image"> </a> </div> <?php endforeach; ?> </div> </div> <!-- End Grid --> <div class="center-block text-center"> <button id="get-more-items" type="button" name="get-more-items" class="btn-vintage">Load More</button> </div> <script type="text/javascript"> var buttonGetItems = document.getElementById("get-more-items"); var indexStart = 0; buttonGetItems.addEventListener("click", function() { indexStart += 9; $.ajax({ url: '<?= $pages->get(1186)->url ?>', type: "POST", dataType:'json', // add json datatype to get json data: ({page_id: <?= $page->id ?>, index_start: indexStart}), success: function(data){ console.log(data); if (data[1]) { //for each element, append it. $.each(data, function(key, value) { $("#gallery").append(value); }); } else { $("#get-more-items").after('<p class="center-block text-center">There are no more items to load.</p>'); $("#get-more-items").remove(); } } }); }); </script> Processing Script <?php $items_array = []; $i = 0; foreach ($pages->get($input->post->page_id)->children->slice($input->post->index_start, 9) as $child) { $i++; $items_array[$i] = "<div class='col-6 col-md-4 gallery-item'> <a href='$child->url' title='View $child->title'> <img src='{$child->item_featured_image->size(640,640)->url}' alt='$child->title Image'> </a> </div>"; } echo json_encode($items_array); I love ProcessWire for hundreds of reasons, but I've been using AJAX more and more, and I'm not liking having to create templates to access scripts. Any advice?

I have an image gallery based on an Image field with about 300 images in it. That caused a little issues with uploading, since it's on a shared host I had to do that piecemeal in order to not overload the server. I kept refreshing the frontend of that page to make sure the server doesn't run out of memory compressing the images, as such an amount obviously requires thumbnails. After 160 images the frontend no longer updates. I can add images to the backend, but they are not shown on the frontend. The images field is not limited in any way. Is there a cap to the amount of images uploaded to a single field? Or any other aspect that might explain such behaviour? The images show up fine in the backend, but when I foreach() through that field I only get 160 results. Any idea what might be going on?

Hi, I am sure this question may been asked but I couldn’t find it in the forum. I am new to using Processwire CMS/CMF. I read great reviews on CMS blog about Processwire. So I decided to give It a try. I am trying to figure out what is the best way to structure a simple gallery. I will also need to be able to catalog the photos. Thank you,

Hi there! I am quite new to processwire and am just finishing my first PW project. I think the whole framework is awesome and could profit a lot from all the tutorials available. One thing that I somehow can't seem to get my head around is working with images and their resizing. I have following scenario: A 'gallery-index' page with its 'gallery' children. Those children have an 'images' field where the user uploads his (often too big) images. I am working with twig. On the gallery page frontend I have a slider, a displayed collection of all the images and a hidden one where I get the source to the original image in a popup. So in total the images will be outputted 3 times in different sizes. First: <div id="slick"> {% for img in page.images %} <img src="{{ img.height(400).url }}" alt=""> {% endfor %} </div> Second: <div class="gallery"> {% for img in page.images %} <img src="{{ img.width(300).url }}" alt=""> {% endfor %} </div> Third: <div class="hidden"> {% for img in page.images %} <a href="{{ img.maxWidth(1024).url }}" data-original="{{ img.url }}"></a> {% endfor %} </div> Now, the loops basically work, and some images are displayed the right way. But not all of there are displayed at all, despite them being there in the DOM. The urls all look right but some will be displayed and some url just go to a small black box image. How comes that PW manages to have different results in displaying the images in different formats? URL of gallery: http://2019.hclaupersdorf.ch/fotos/hc-laupersdorf-vs-ruschlikon-chiefs/ (there are more in the DOM than displayed) URL of 'not working' image: http://2019.hclaupersdorf.ch/site/assets/files/2361/20180616-rueschlikon-21_42049612175_o.300x0.jpg Furthermore, whenever this error occurs (which usually is at every page request on the gallery page), the DOM doesn't fully load. My JS for init the slider or the popup won't be loaded and the page is basically displayed half-loaded. Any ideas or suggestions on how to work around it, best practice when handling images & galleries? Thanks!

Hi! After temporarily using Module Image Extra, which I completely removed, I had some troubles with my imagefield (unused table columns). So I just imported a previous version of this column via PHPmyAdmin, which worked pretty well. Anyways, in Processwire Backend all image tags are gone, although they are OK in the database. Other image related things work (thumbnail, title etc are OK). Is there any way to recreate all the images or something? Or may this be an cache-related issue? Thanks in advance ?

Hi, There's something happening in ProcessWire that doesn't compute abd it has to do with images. Situation: On the homepage template there's a repeater that takes two images to build a slider: slide_image: A wide image for desktops slide_image_mobile: A more "verticalized" image for small screens Now I have this code: foreach($page->home_slides as $slide) { // Create desktop slide if(isset($slide->slide_image)) { // Create desktop slide $slide_image = $slide->slide_image->size(1170,400); // Create mobile slide if(isset($slide->slide_image_mobile)) { $slide_image_mobile = $slide->slide_image_mobile->size(1048,800); } else { $slide_image_mobile = $slide->slide_image->size(1048,800); } ?> <div class="slide-content"> <a href="<?php echo $slide->link; ?>" class="slide"> <img src="<?php echo $slide_image->url; ?>" class="img-fluid d-none d-md-block" title="<?php echo $slide->slide_title; ?>" alt="<?php echo $slide->slide_title; ?>" /> <img src="<?php echo $slide_image_mobile->url; ?>" class="img-fluid d-block d-md-none" title="<?php echo $slide->slide_title; ?>" alt="<?php echo $slide->slide_title; ?>" /> </a> </div> <?php } } On my dev server, the small image is detected and placed in content, however in my production server this doesn't happen. I've double checked fields names and the fields contain images. I've even imported the database into the Dev Server. I don't have any clue why it works locally and not in server. Can anyone shed som light? Thank you!

I have 2 repeater types working with the Repeater Matrix. To keep things simple, I have image gallery a downloads gallery. I can't quite figure out how to echo the contents from within a product_gallery. I can get the code below to display the text 'An image gallery' but not the bunch of images within this. I'm not sure though if it's my variable trail or my nested echo statement. <?php foreach($page->components as $item) { if($item->type == 'product_gallery') { echo " An image gallery..."; foreach($product_gallery->images as $photo) { echo " An image <image src='{$photo->url}'> "; } } else if($item->type == 'downloads') { echo " A download gallery... "; } } ?> Thanks P

I created this module a while ago and never got around to publicising it, but it has been outed in the latest PW Weekly so here goes the support thread... Unique Image Variations Ensures that all ImageSizer options and focus settings affect image variation filenames. Background When using methods that produce image variations such as Pageimage::size(), ProcessWire includes some of the ImageSizer settings (height, width, cropping location, etc) in the variation filename. This is useful so that if you change these settings in your size() call a new variation is generated and you see this variation on the front-end. However, ProcessWire does not include several of the other ImageSizer settings in the variation filename: upscaling cropping, when set to false or a blank string interlace sharpening quality hidpi quality focus (whether any saved focus area for an image should affect cropping) focus data (the top/left/zoom data for the focus area) This means that if you change any of these settings, either in $config->imageSizerOptions or in an $options array passed to a method like size(), and you already have variations at the requested size/crop, then ProcessWire will not create new variations and will continue to serve the old variations. In other words you won't see the effect of your changed ImageSizer options on the front-end until you delete the old variations. Features The Unique Image Variations module ensures that any changes to ImageSizer options and any changes to the focus area made in Page Edit are reflected in the variation filename, so new variations will always be generated and displayed on the front-end. Installation Install the Unique Image Variations module. In the module config, set the ImageSizer options that you want to include in image variation filenames. Warnings Installing the module (and keeping one or more of the options selected in the module config) will cause all existing image variations to be regenerated the next time they are requested. If you have an existing website with a large number of images you may not want the performance impact of that. The module is perhaps best suited to new sites where image variations have not yet been generated. Similarly, if you change the module config settings on an existing site then all image variations will be regenerated the next time they are requested. If you think you might want to change an ImageSizer option in the future (I'm thinking here primarily of options such as interlace that are typically set in $config->imageSizerOptions) and would not want that change to cause existing image variations to be regenerated then best to not include that option in the module config after you first install the module. https://github.com/Toutouwai/UniqueImageVariations https://modules.processwire.com/modules/unique-image-variations/

Is there a way to make JPGs progressive by default via the API? I've added the following to my site/config.php file but user-uploaded images are often displayed as non progressive. $config->imageSizerOptions = array( 'upscaling' => true, // upscale if necessary to reach target size? 'cropping' => true, // crop if necessary to reach target size? 'autoRotation' => true, // automatically correct orientation? 'interlace' => true, // use interlaced JPEGs by default? (recommended) 'sharpening' => 'soft', // sharpening: none | soft | medium | strong 'quality' => 95, // quality: 1-100 where higher is better but bigger 'hidpiQuality' => 60, // Same as above quality setting, but specific to hidpi images 'defaultGamma' => 0.5, // defaultGamma: 0.5 to 4.0 or -1 to disable gamma correction (default=2.0) ); Thanks
