Fuxtape mode should show "album art"

[jamiew]

Maybe 1st image gets used as album art? Or only allow 1 image...

Perhaps as a % of directory contents? e.g. 90% music but 10% images, show images as a small row on top. If it's only less than 90% music (50% music?) use the inline audio player instead of Fuxtape mode, i.e. these are probably short samples and clips
