After the upgrade to f43 some file types in the file manager don’t get thumbnails anymore.
.jpg/.jpeg and .png don’t show thumbnails, but .pdf files do. See screen shot.
What can I do to get thumbnails back for all file types? Thanks!
This thread suggests installing glycin-thumbnailer - does that help?

In fact, this package should get installed by default on Fedora 43. I’m not sure why there are a few circumstances where it’s not.

Hi,
i have the same Problem with the thumbnails, i’ve tried all above mentioned methods, still no thumbnails. I even removed the packages and reinstalled them, still nothing.
Would love to her some other possible solutions!
thx
If thumbnails failed to generate once, they are not retried again. So you might need to purge the “failed” ones from the cache for the thumbnailer to retry generating thumbnails. Running this command should do what you need (if this is indeed the case):
rm ~/.cache/thumbnails/fail/gnome-thumbnail-factory/*
okay on my pictures folder it seems to work, but when i try to open folders on my nas it wont show the thumbnails, might be a problem with the network?
maybe because it shows access rights > “noone” ?
it is a samba share if this helps 
That’s definitely strange …
Though beware that generating thumbnails for “remote” files is disabled by default, you might need to enable that in the application settings.
alright, i fixed it. had to properly mount the nas in fedora via terminal, now it shows proper access rights and it generates thumbnails!
thank you for your help!
maybe it will help someone with the same problems
i used some help from this site: Connecting to a Network Drive (SMB/CIFS) on Fedora Linux – RaySSL
