bluebrother, music.apk is not the problem, its the gallery that doesn't handle folder.jpg properly(by ignoring it). would be nice if rockbox supported a custom aa filename, configurable in config.cfg called cutom-aa-filename=whatever.jpg
then developers wouldn't have to compile a larger list of possible AA filenames.
torne, never heard of .noimage, doesn't do anything on my android, tried putting that in the root of my music folder.
