I originally used a combination of local files with an external sync application but switched to jellyfin to save space on my phone. While I was using local files I liked how the metadata showed up-to-date images, even one from spotify that was updated by the artist just yesterday. I want to use the same metadata provider in my jellyfin server, so I would appreciate it if you would let me know. If it is something you cannot share I understand that.
Problem solved:
Jellyfin’s only image provider has horrendous images
Is it possible to add an option to disable deezer as image provider, or option to change priority to set, for example, lastfm as first? Unfortunately in some cases deezer use not quite correct photos for artists or simply album covers.
