[MarkvanJaarsveld]

Trying to upload an Image

BLANK Screen and url ​https://wordpress.org/photos/wp-admin/admin-ajax.php

This is the 4th time I have encountered this error and the "failed" submissions are now stuck in my moderation queue, so only able to upload 1 image currently, and if I have another failure I would be unable to upload anything,...details below

There is a limit of 10 MB for uploads, 12 is too large.

Question: Were all your photos this large? If so, then that would explain some things we've been seeing.

Yes! All the "failures" had a file size greater than 10MB.
Dimensions of 6000x4000 - Most of my image files are between 10 -15MB.
I have reduced the dimensions of the images to 4000x3000 same resolution and the new files upload without a problem.

I will keep this 10MB limit in mind for future uploads.

Many thanks

I have checked back on previous successful uploads, and I did manage to upload image files with size greater than 10MB
Example 13.8 MB :- ​https://wordpress.org/photos/photo/6556217670/ without a problem??
Another 12.7 MB : ​https://wordpress.org/photos/photo/9106210cf0/
14.9 MB : ​https://wordpress.org/photos/photo/1246210ce9/

I'm experiencing this for photos not larger than 10MB: https://meta.trac.wordpress.org/ticket/6439

I suspect this is not directly related to file size but rather something is failing when they're getting the information from the picture with PHP, and it only fails in some particular scenarios (which I have no idea what are).

My experience was that the Dimensions of the Images(not file size), where exceeding the limit of 7500x7500 pixels, and that caused the failures,...

There's been an uptick in reports in the last month of this, I suspect this might be related to the fact that we generate the resized versions of the images, and as of ​#core55443 also webp images. That corresponds with the OOM fatals being during image-save ​class-wp-image-editor.php:601.

To take ​https://wordpress.org/photos/photo/33462fcf29/ for example, the following files were generated:

33462fcf296c37071.52699659-300x225.jpg

although some images, such as ​https://wordpress.org/photos/photo/91462f0d89/ don't generate any resized variants / webp's - the thumbnails (including original, and 2x in the srcset) and singular view all use the full size image.

(Both of the above images were uploaded within the last 24hrs)

although some images, such as ​https://wordpress.org/photos/photo/91462f0d89/ don't generate any resized variants

This has the additional side-effect that the "Download" dropdown lists the various sizes, but all links point to the original file rather than a resized variant.

The affected uploads in that group appear to be those where the webp conversion ran out of memory on the smaller resizes, but had enough memory to complete the initial conversion of the original fullsize image.

These OOM upload errors are also what's causing the Photo Moderation admin to show incomplete uploads, no photo shown and likely the photo caption of Untitled post submission.

In 12023:

Photo Directory: Disable jpeg -> webp conversions, due to significant increased memory usage causing uploads to fail.
