Request: script to update thumbnail of movie extras #441
Description
I like to set thumbnails for extras since the default thumbnails are just random frames from the video.
Currently I manually browse the plexmediaserver/Library/Application Support/Plex Media Server/Media directory by recently added and replace the thumbnail image. This works fine when I've recently added an extra and no other thumbnails were generated at the same time.
I've seen comments online (see this comment by blacktwin and this comment by SwiftPanda16 ) that it's possible to do this via the API.
I'm happy to contribute the script, but I couldn't figure out how exactly to do it. The Extra object in plexapi doesn't support a method like uploadPoster() or uploadThumb(), and there doesn't seem to be a way to find the location of the local thumb file in plexmediaserver/Library/Application Support/Plex Media Server/Media based on the Extra object either.
