Now that image files are moved with the music files when restructuring your folders, I can imagine being able to set the name of the image file that Jaikoz uses for the cover art for an album.
Say you have 3 or 4 or more images in an album folder, rather than storing all those images with each and every song file, you could designate which file name to look for when adding art to the file. Only the matching jpg would be stored with the song file, and the others would just move along with the folder when restructuring.
