Bug description
Nextcloud nicely generates images to be shown in the web interface, also there is an image editor available. When one changes something in an image, the preview doesn't seem to update..
Steps to reproduce
Expected behavior
One would expect to see the changed image..
FIX SUGGESTION
I have this problem in my coding sometimes too. The problem is the caching of the browser. There is a little trick to fix this:
The image URL is something like:
[URL]/core/preview?fileId=964&x=1920&y=1080&a=true
When one would add something unique, like the file time ('storage_mtime' in 'oc_filecache' would seem to be perfectly suitable for this) then the URL becomes a new one and one can force an update. Something like:
[URL]/core/preview?fileId=964&x=1920&y=1080&a=true&mtime=1674741268
Then that URL gets cached (do not add a random number, that would strain the caching unnecessarily)
