Jellyfin displaying the same thumbnail for all episodes in a season

I don't have to use NFOs. My machine has a good processor and fast internet so if there is a better way of handling metadata, I'm happy to do that. What do you suggest?

Just to clarify what I think I am hearing, if you DON'T use NFOs and local images that doesn't mean Jellyfin is downloading images every time you open a page.  If you don't use NFOs or have images in your media directories, Jellyfin will just save all the metadata in its database and all the images in a centrally located data directory.

NFOs and saving images with your media is important if you A) use Kodi and you don't use any Jellyfin plugins in Kodi and/or B) preserving/making portable customized metadata and images, just in case your Jellyfin database is corrupted.

Personally, I dislike the clutter of NFOs and images in my media directories and just have Jellyfin centrally save and manage the metadata.


But, that's a personal preference.

If you want to keep NFOs, you can try to rescan and select "search for missing metadata" or go nuclear and start over with "replace all metadata".  Maybe start with a single season of a show before doing that for your whole library.
