Only load uploaded media as image when it is an image - #325

Summary

MediaRepository::storeMediaToModel currently calls ImageFactory::load(\$request->media->path()) on every uploaded file in order to populate original_dimensions for image collections. The mime-type check on the line below only guards using the result — the load itself runs unconditionally.

For non-image uploads (PDFs, ZIPs, etc.) this throws Spatie\Image\Exceptions\CouldNotLoadImage from GD's imagecreatefromstring() and the upload fails with a 500. As a result non-image files can no longer be attached to media collections (e.g. a \$form->file('file')->accept('application/pdf') PDF field).

Example error from production with a PDF upload to a file collection:

production.ERROR: Could not load image at path `/tmp/phpXXXXXX` :
imagecreatefromstring(): Data is not in a recognized format

Change

Move the ImageFactory::load() call inside the existing Str::startsWith(\$mime, 'image') guard so it only runs when the upload actually is an image. Behavior for image uploads is unchanged.

-        \$image = ImageFactory::load(\$request->media->path());
-
         if (Str::startsWith(\$request->media->getClientMimeType(), 'image')) {
+            \$image = ImageFactory::load(\$request->media->path());
+
             \$customProperties['original_dimensions'] = [
                 'width'  => \$image->getWidth(),
                 'height' => \$image->getHeight(),
             ];
         }

Test plan

• Upload an image (jpg/png) via a media \$form->image() field — custom_properties.original_dimensions is still populated.
• Upload a PDF via a \$form->file() media field that accepts application/pdf — request succeeds, file is attached.
