Thread:Project:Support desk/Image Thumbnail Not Being Created When Image Used In Article/reply (2)

What other processes would be involved in the generation of a thumbnail by the 404 handler if that is the case, and the one that is created during the process of uploading a new file? I would have assumed (and could very easily be wrong) that in both cases the resizing would be handled by the GD library within PHP. Permissions are sufficient for the php-fpm process to write to the thumbs dir at the time of upload, so I can't think what would have changed. Linux also isn't my forte, but I would expect to see a permission error shown in the system log of CentOs if not in the PHP log itself, and have found nothing in either.

I will look further into the 404 handler though, thank you for that lead. Any extra explanation you can provide in regards to my above comments would be appreciated.
