Getting Jellyfin to Recognize Local Images

[Deucenukem]

I'm working on building my library, and am using a lot of custom images for posters and thumbnails. Currently the images are saved into the same folder as the video file. How can I set this up so that Jellyfin will always recognize an image as the poster, or the thumbnail?

I went through and set a bunch of them manually, and then realized I wanted to change my folder naming scheme a bit, and will need to manually add them all again. I'd like to avoid this going forward, if possible.

Thank you
