No offense to OP, but I still say it sounds like a lot of work for a feature only one person seems to want.
How does artwork rotation work now? Can they be files in a subfolder of the album folder or do they have to be embedded?
My idea was simple:
1) If an album (track) it determined as game/movie soundtrack
2) then display screenshots/movie stills/ covers in slideshows (or in views- fe when I group in main panel by Game - game cover should be displayed)
So far most of the steam in the discussion went into 1).
The sources for 2) can be either local or online (fe.
http://www.moviestillsdb.com/,
http://www.movieposterdb.com/,
http://vgimg.com/,
http://www.gametdb.com/ - first hits from Google, damn, they have everything covered in these internets). In case of local, there must be a way to tell what is movie poster(s), movie still(s), game cover(s) and game screenshot(s), to be used in proper context.
That's it.
Judging by the number of replies I don't think this is one of rather forgotten ideas.
BTW, in case of games hardware platform can also make a difference
