The actual program works but in arch linux it won't change the background images. defaults straight to solid colour. also despite specifying a user image that user image won't appear on log in screen.

Ran into the same thing on Fedora 37, the root cause for me was due to the parent folder's permissions not being world readable.

• Same on Fedora 37
  • Root cause was permissions issue, needs to be world readable and all directories which are parents need to be world readable as well. Moved file from /root to /opt/wallpapers/ and ensured permissions were correct.
