Hi,
i realized that there could be more than one image in an mp3 files. With "eyeD3" (a command line tool for linux) i can add images with
type can be "FRONT_COVER" or "ARTIST" (and other). As long as the descriptions are different i can add as much images i want.
Lets say i add an album cover and an artist cover. Can Poweramp use both images? the artist cover in the artist view and the album cover in the view where i see all albums of an artist? I tested that but Poweramp is using the album cover of the first album in all views.
