Hello Gentlemen and Ladies. I have not posted for a while but now i need your help figuring out some things. The Documentation has come a long way and i love it. Though on the page: https://processwire.com/api/ref/pageimages/ I am trying to figure out if when i want to add an image to an existing image field with multiple images alldready in it and using the method $page->images->add() <?PHP /* get the images object array for the Page */ $myPageImg = $page->images; /* define the image to add */ $newImg = 'http://www.somesite.com/image.jpg'; /* Thanks Autofahrn, forgot about the output formating */ $page->of(false); /* create a new Pageimage object with the given URL and add to the Pageimages array */ $myPageImg->add($newImg); /* save the page */ $page->save(); ?> I am pretty sure i missed a few steps in the code above? Is that string suppose to be an URL like "http://www.somesite.com/image.jpg" and the method will automaticly download the image and create an Pageimage Object and add it to Pageimages array or does it have to exist on the host first and i supply a file path to that image? I guess im confused about that, hope you guys could clarify that for me. And if it needs to be allready downloaded to my host before adding the image, what would be the best API methods for that task? Just point me in the right direction and i will figure it out. Sorry for the bad explaination but i could not figure out a better way of asking. Thanks in advance. /EyeDentify -
Hi guys. I would like to show only the first image as a preview of a slideshow. The code below shows the first image but is repeated. Do you know a solution? Thank you //Call image foreach($story->galleria as $img) { echo "<img src='{$story->galleria->first()->url}' alt='{$story->galleria->first()->description}'>"; }

Hey, I am very new to processwire and bootstrap. I have a field (text area) and there I want to be able to insert an image which is responsive. I tryed it with Source but in the end the page doesn't seem to like it when I insert in Source the following code <img src="<?php echo $homepage->content_img->url; ?>" class="img-fluid" alt="Responsive image"> What can I do to make it possible to insert reponsive images in a text area? Thank you in advance. Marcel

I'm doing an artist site and they want to be able to upload a large .tiff to their portfolio. I need to keep to a copy of the original file in the server for the art distributers, and of course serve jpg in the web front end. I had the idea of extending the file or image upload input so that if the image is tiff, keep it, and also convert it to jpg, so I could access through something like $image->originalUrl or $image->size(100, 100)->url I was wondering if you thought this a good idea, or if i'm over-engineering something that could be done simply. Also, I've never extended an input, so any examples are welcome. Thanks!

Hi, I'm stuck since hours and don't know what to do. Here is my Problem: I try to generate Previews of PDF using imagick. I have 4 PDF, I generate a preview of the first page of the pdf, save it to a temporary file and want to import it using the api into an image field. It works for the later 3 pdf but not the first. I add it to the image field and save it. Inside the function that saves it, the image is stored in 'data' as well as in 'itemsAdded' but as soon as i leave the function, its nowhere to be found. Process: 1. create previewimage using imagick and create Pageimage > works 2. add image to filed 'filepreviews', returns Pageimages array with image added > okay 3. save page > returns true 4. Outside renderPreview method, image is not anymore in 'filepreviews' // mymodule // … // foreach($files as $file){ $preview = wire('page')->filepreviews->get('name*='.$file->basename(false)); // if there is no preview image… if (!$preview instanceof Pageimage) { $this->renderPreview($file) // we create one using $this->renderPreview > should return true on successful save dump(wire('page')->filepreviews); // my Image is nowhere to be found $preview = wire('page')->filepreviews->get('name*='.$file->basename(false)); } // end for each // render a preview of an otherwhise not supported file format // return true if sucessfull save private function renderPreview($file) { $page = wire('page'); // get path to temporary image $tempFile = $path.$file->basename(false).'-preview.jpg'; // … some imagick code // … and save it: $imagick->writeImage($tempFile); $img = new Pageimage($page->filepreviews, $tempFile); $img->description = $file->basename(false); // destroy temp image unlink($tempFile); // this is my Pageimage, all good… dump($img); // save image, my Pageimage can be found in data and itemsAdded – all good dump($page->filepreviews->add($img)); $page->of(false); $success = $page->save(); // sucess = true dump($success); return $success; } Second question: Would there a generally better approach? Like using pageFiles somehow. Goal is to be able to use the image api like scale etc – I don't generally need the images to be stored in an image field.

I want to use the API to duplicate an image from one field to another (on the same page). The duplicated image should be a new file so both fields should not point to the same physical file. The field that holds the image that I want to duplicate is called 'image_front' and the duplicated image should go to a field called 'image_thumb'. Any image that is already attached to image_thumb should be removed because it should hold only one file. The same goes for image_front, it should have only one image. Here's what I have so far: $original = $page->image_front; $file = $original->getFile($original); $new = $original->clone($file); $page->save(); $page->image_thumb = $new; $page->save('image_thumb'); This works in the sense that the image is successfully cloned but it is attached to both fields so both fields end up have their original image plus the cloned image. 'Image_thumb' should only have the cloned image and 'image_front' should only have the original image. What would be the best way to remove those images and am I even approaching this correctly?

Hello guys. I feel a bit ashamed of this fact but I just needed to add an image with some text wrapped around it using CKEditor and I simply can't achieve that. I have an image field attached to the template (called images) and it is showing promptly the uploaded images. I am able to manipulate the image and I set its alignment to left side. Then I add some text and I can see in CKEditor that the text is properly surrounding the image. However, once I save the page and view it, it shows the text under the image or only a line is staying asside the image and the rest is under the image again. As far as the field used for the text (body) is set to TextMultiLang and I did not added any text formatters and chose the content type to be HTML/Markup. In my CSS I've added some of the PW styles for the alignement as per some posts here but that did not help either. Something I am missing again?

I want to split my output of an image array, see my code here: <div class="row"> <?php foreach($page->umf_imgs as $image) {echo "<div class='one-fourth column refs'><img src='$image->url'></div>";} ?> </div> <div class="row"> <?php foreach($page->umf_imgs as $image) {echo "<div class='one-fourth column refs'><img src='$image->url'></div>";} ?> </div> <div class="row"> <?php foreach($page->umf_imgs as $image) {echo "<div class='one-fourth column refs'><img src='$image->url'></div>";} ?> </div> The number of images is 11, but I only want to add four in a row. Is it possible to grab them, e.g. image 1-4, image 5-8, image 9-12?

Inspired by the "max megapixels" option for the client-side image resizer, I made a simple module that adds target megapixel resizing for Pageimages. Image Megapixels A module for ProcessWire CMS/CMF. Adds methods to Pageimage objects useful for resizing to a target megapixel value. Example use You are creating a lightbox gallery of images with different aspect ratios. For the enlargements, rather than setting a fixed maximum width or height you want all the enlargements have the same size in terms of area, allowing a panoramic image to be wider than a square image, for instance. Another use case is sizing a gallery of sponsor logos. The supplied logos are different aspect ratios but you need to ensure the logos are sized so each has equal prominence on the page. The effect of resizing three different aspect ratios by the same megapixel target value can be seen in the screenshot below: Installation Install the Image Megapixels module. API // basic usage $pageimage = $pageimage->megapixels(float $megapixels); // usage with all arguments $pageimage = $pageimage->megapixels(float $megapixels, array $options = []); Example: foreach($page->images as $image) { echo "<img src='$image->megapixels(0.8)->url' alt='$image->description'>" } If needed you can supply an array of options for Pageimage::size() as a second argument. Getting dimensions If you just want to get the height and width dimensions needed to size an image to the given number of megapixels you can use the Pageimage::megapixelsDimensions() method that this module also adds. It returns an array with width and height as keys. Example of how this could be used to output a gallery of logos: foreach($page->logos as $logo) { $dimensions = $logo->megapixelsDimensions(0.01); $width = $dimensions['width']; $height = $dimensions['height']; $width2x = $width * 2; $height2x = $height * 2; echo "<img src='{$logo->size($width, $height)->url}' srcset='{$logo->size($width, $height)->url} 1x, {$logo->size($width2x, $height2x)->url} 2x' alt='Logo' width='$width' height='$height'>"; } https://github.com/Toutouwai/ImageMegapixels https://processwire.com/modules/image-megapixels/

Hi all, I'm really new to ProcessWire, maybe I missed the solution in the documentation. I'm working on a site which involves a lot of image upload fields, and I'm always getting many timeout errors. I'm pretty sure it's because I generate too many variations on a single page load (around 20 images with 7 different sizes, for them to be responsive). I can't use ImageSizerEngineIMagick to help (my host doesn't support it). I was wondering if there was a way to hook to the process of client-side image resizing (https://processwire.com/blog/posts/processwire-3.0.63-adds-client-side-image-resizing/) to generate the different variations (as it seems really faster). If not, is there a way to generate the different variations on upload and not on page load ? Any ideas and suggestions are welcome! -
Hi everybody, i am looking for a way to "mark" only one image in a imagesfield with multiple images, so i can request it on the homepage. I am making a collection of pages with images and on the home page i want to display one image out of every childpage (not the first image of every child) "I have been thinking on a switch next to the images so that i can "mark" the image, only one image in the imagesfield can be "marked" Any ideas how to archive this ?

It would be great if 'choose file' in the image field would be able to handle other input sources than only the client's OS file manager; Amazon S3/cloud storage, Dropbox, an image folder on an intranet, another folder on the same server where PW is installed, whatever. It would be super convenient if you could just upload images to a folder/directory in the templates folder or root, without any processing, and be able to access that as a source option in the image field. Any way to make that happen? I had started a thread about this here. BitPoet posted a very helpful partial solution specifically for Zenphoto, but it would be great if there was a more source agnostic solution built into Processwire. Letting Processwire download images from any external media gallery/repository would be a good alternative to having a full centralized Media Manager. Or am I missing something that would make this impossible/a bad idea? Edit: Robin S has a module that adds one alternative input option.

I have a "strange" issue with my dev set up, that I just noticed today. I set up an image field named "dev_gallery" and checked the "use tags" option when setting it up. I went to add a couple image to the field, and noticed that the tags option is not displaying at all for the image. Currently, the description field is the only current field on image edit. Have I missed a basic setting to enable this? I am currently using PW 3.0.62 as well.

Hello dear community I have a problem with a front edit possibility inside a OWL gallery. The thing is, normally you do a double click to edit something directly on a page. In my case a single click opens up a picture inside a gallery, so I can't "hit" the editing. <div class="demo-gallery"> <ul id="lightgallery2" class="list-unstyled row"> <li class="img-md-12 mb-12 mb-sm-12 mb-md-12 mb-lg-12 mb-xl-12 col-12 col-md-12 img-fluid full-height" data-responsive="" data-src="<? echo $page->page_home_owl_00_img->url; ?>" data-sub-html="<h4><? echo $page->page_home_owl_00_h4; ?></h4><p><? echo $page->page_home_owl_00_p; ?></p>"> <a href=""> <img class="img-responsive" src="<? echo $page->page_home_owl_00_img->url; ?>"> </a> </li> <? foreach($page->children('template=9dk-owl-home') as $item): ?> <li class="img-md-6 mb-3 mb-sm-3 mb-md-3 mb-lg-3 mb-xl-3 col-12 col-md-6 img-fluid" data-responsive="" data-src="<? echo $config->urls->templates ;?><? echo $item->page_home_owl_01_img; ?>" data-sub-html="<h4><? echo $item->page_home_owl_01_h4; ?></h4><p><? echo $item->page_home_owl_01_p; ?></p>"> <a href=""> <img class="img-responsive" src="<? echo $config->urls->templates ;?><? echo $item->page_home_owl_01_img; ?>"> </a> </li> <? endforeach; ?> </ul> </div> I tried any variants of options C and D from this page: https://processwire.com/api/modules/front-end-editing/ Are there any hints for me, what I can do? Any help is highly appreciated! Best from Munich in Germany

Please see attached screenshot. The image on the left is the original image that was uploaded. The image on the right is what it looks like after it was resized to fit into a template by ProcessWire using <img src="<?php echo $featured_image->size(854,0)->url ?>" /> This is a significant loss of color for these images. Is there a way to prevent this from happening — other than forcing client to crop the images to the exact dimensions ahead of time, and not resizing with PW?

Hello together, I have a problem with the image field and in my case it seems that there is a limit of how much images can be in such field. The following case: I have around 20 pages. Each has a usual image field, where I can upload an unlimited number of images (array). Most of the pages got 50-200 images but one page got 411 images (I know, it’s much ) Now, when I change the order of one image (let’s say I drag & Drop the first image after the third) or delete one image by clicking on the trashcan, everything runs fine. BUT when I click SAVE the image won’t be deleted or moved to it’s new place. You can change anything else on the page - I have a text field there - and save it, no problem. Interestingly I can add (upload) new images but I’m not able to delete or move them. - The file size of the images are between 200kb and 1.7MB, RGB, JPGs. - When I duplicate the page and try to delete/move I got the same problem. - I also created a whole new page and got the same problem - Also tried a different server (virtual and online): same problem - ProcessWire 3.0.62 So, is there a limited to the images field? Any clues except limiting the image files to max. +-200 images? Thanks so much in advance and have a great weekend. Thomas

I am new to PW, and am trying to get an image to display, from a field in my template. Here's the code I'm using: <?php $image = $page->home_header_image; echo "<img src='{$image->url}' alt='{$image->description}' />"; ?> I'm following the tutorial on this here. When I save the template and reload the page, the path to the image is incomplete. If just echoes: <img src="/site/assets/files/1/" alt=""> It omits the name of the image, at the end of the path. Here's the site I'm working on: http://dev.delucaswpg.webfactional.com A couple caveats: I'm using ProcessWire 2.3.0 (tried updating the site and everything went berserk because of some plugin dependencies; point being: I can't update to the latest PW). I tried using the ->size thing and it gave me an error, saying it couldn't use 'size' in this context. Which I also thought was weird. Any ideas? Thanks!

Hi, I have a big image in my image field and want to resize it to 2280px before showing it to the user. Most images are fine and showing as expected, but with one I have the following error; Error: Out of memory (allocated 159383552) (tried to allocate 12288 bytes) (line 243 of /htdocs/process/wire/core/ImageSizerEngineGD.php) Why is this with one image and not with the other ones, and how to solve this?

I have a problem realizing a picture gallery with albums using repeater fields. Here is what I have: - The repeater field 'repeater_gallery' for all the albums - A text field 'album_name' in the repeater for the album name - An image field 'album_images' in the repeater for all the album images Now I'd like to pick a small selection of images (say 4) of ALL albums randomly and present them with their associated album name. How can this be done with the described repeater setup? Or is there a better way to realize such a gallery without repeaters? Thanks in advance for a little help.

Hi all, in the backend of ProcessWire it's possible to define a maximum width and height for images. If you upload an image, it will be resized automatically. I find this feature very handy to safe space. Very often users upload images which are much bigger than needed. On my application users can upload their images via the frontend. But if you upload images using the API, images won't be resized automatically. Is there any way to do this? Currently that's my code: if ($_FILES['thumbnail']['name']) { $upload = new WireUpload('thumbnail'); $upload->setMaxFiles(1); $upload->setOverwrite(true); $upload->setDestinationPath($lesson->video_image->path()); $upload->setValidExtensions(array('jpg', 'jpeg', 'png')); $lesson->video_image->removeAll(); foreach ($upload->execute() as $file) $lesson->video_image->add($file); } Thanks very much!

I have a page that's throwing an error because some of the pages in the for each loop don't have an image The docs say it's wise to check that an image has content and only then try to output something. I thought the following would work with the if($image) below. $products = $page->children(); foreach ($products as $prod){ $image = $prod->images->first(); echo" <div > <div class='prod-ov-wrapper'>"; if($image) echo " <a href='$prod->url'> <img src='{$image->height(160)->url}' class='prod-preview'> </a>"; echo" <div class='prod-ov-text'> <strong>Part No:</strong>{$prod->title} <br/> {$prod->prod_summary} <a href='$prod->url' class='uk-icon-button' uk-icon='icon: chevron-right'></a> </div> </div> </div> ";} What am I overlooking here? Thanks
