api created occasionally broken thumbnail images

Recommended Posts

Hi there,

in an image gallery with the following code

foreach ($page->bilder as $bild) {
        $thumbnail = $bild->size($page->thumbnail_size,$page->thumbnail_size);
...

a JS gallery function broke down with the error message: "unitegallery.min.js:6 Uncaught Error: Can't get image size - image not inited."

I looked into the /assets/files/nnnn/  folder and found 5 images (of about 16 or so) having api - generated version with only 42 Bytes. 

4 of them had the string "....0x0.jpg" in their filename, but the 5th had an unsuspicious filename. They were all generated within the same second, according to their timestamp.

In the backend, they could neither be opened nor deleted. Via FTP they could be deleted. This fixed the problem with the gallery. 

In the /logs/exceptions.txt I found lines like

leute_im_boot.0x0.jpg - not a recognized image (in /wire/core/ImageSizer.php line 257)

In the errors log I did not find anything apparently related.

Did anybody observe something similar?

cheers - - -

Seen such 'blank' images before. Happened when PHP run out of memory to process a big image. It always annoyed me that ImageSizer insisted on creating the blank image rather than giving up  :P . About not being able to delete them...it means they were still in memory being processed, basically, in a crazy loop I suppose. So, check your memory, or your image size, or use $pages->uncacheAll() after each resizing or increase your set_time_limit(60)/ or 30 maybe, inside your loop to avoid timing out or a combination of all these tricks...With the latest ImageSizer though I think (?) such issues have been resolved...don't quote me though...haven't tested it yet :-)

Yea I saw you can use imagemagick for processwire now somewhere. This will get round the out of memory issue.

      Hi, on a site I want to disable access to original images and only allow to access thumbnails and watermarked image variations.
      EDIT:
      A good solution for protecting original images can be found a bit down in this thread:

      I seem to be running into a repeated fatal error in a fresh PW install version 3.0.148. I can't quite put my finger on the pattern but it seems to be around deleting image fields or removing images from certain image fields.
      This is the trace from the log generated by trying to save a page and delete an image from an image field:
      Fatal Error: Uncaught Error: Cannot access protected property Pageimage::$original in /wire/core/PageimageVariations.php:256 Stack trace: 1. /wire/core/Pageimage.php(1327): PageimageVariations->getInfo() 2. /wire/core/Wire.php(386): Pageimage->___isVariation() 3. /wire/core/WireHooks.php(823): Wire->_callMethod() 4. /wire/core/Wire.php(450): WireHooks->runHooks() 5. /wire/core/Pageimage.php(1369): Wire->__call() 6. /wire/core/Pageimage.php(399): Pageimage->getOriginal() 7. /wire/core/WireData.php(333): Pageimage->get() 8. /wire/core/PageimageVariations.php(256): Pro Line 256 of /wire/core/PageimageVariations.php Earlier in the day I was experimenting with custom fields for images for the first time and kept running into this error, thinking it was me using this feature wrong and not having time to read up I deleted the custom image fields template and went about my business. So now I don't know if I triggered an issue or whether it was never related to the custom image fields in the first place?
      Any ideas?

      I'm using some Custom fields for images: 
      https://processwire.com/blog/posts/pw-3.0.142/#custom-fields-for-files-images

      When I save the page, and return the fields are blank. When I re-add the text to the fields and save again then the fields save as expected.

      I know this is stated as being quite experimental but it's super useful feature I'd love to get working correctly.
      I have fields that are CKEditor fields but have overidden this on the image specific template. I've also tried it with regular text fields and I get the same bug.
      (currently using Processwire 3.0.155)
      **UPDATE**
      I've found this issue is specific to editing on pages using the PageTable fieldtype. The fields are not saving when I save the page in the PageTable.

      Displays image tags overlaid on the thumbnail using customisable colours. This makes it easier to see which images have which tags without needing to open the edit pane for individual images or changing to the list view.
      Screenshot

      Usage
      Enable tags for one or more image fields. Install the Image Thumbnail Tags module. Optionally configure colours for any of your tags.

      Hello dear PW gurus.

      I have stumbled over a strange error that i all of sudden got when trying to upload an image to a images field on a page.
      There where images allready stored in the field that i wanted to keep, but during the upload the error apear and after that all images are gone from the field and i can´t upload any, i just get the error every time.
      I am running ProcessWire 3.0.153 dev.
      Update:
      After looking in the assets folder i find the folder for the page and the image files seems to be there including the ones i tried to upload when the error occured.
      But they don´t show up in the images field in the page editor.
       
      The error reported:
       
      SQLSTATE[01000]: Warning: 1265 Data truncated for column 'ratio' at row 1 And here is a screenshot of the event:

      The TracyDebugger Error reporting:

      I hope you fine folks could point me in a direction.
      But it seems our old pal set_time_limit() is back.

      Regards, EyeDentify
