Artwork

[timster]

Minimserver does not have this possibility I'm afraid, except for playlists. You could try browsing in folder view though for artists. I have artist jpgs in all my artists' folders - when browsing in folder view they appear for each artist but only because they are sorted in the directory like yours. You wouldn't have anywhere to put a genre image.
For your playlists, if a .jpg exists with the exact same root name as a corresponding .m3u then it will be shown in the playlists container.
