If all the songs will contain the same image art, you could do this: Go to All Tracks View, then select the songs that are in that CD, right-click, and go to Properties. Tick the 'Compilations' Tab, then go back to Album View, they should now appear as an "individual" album. Now you can attach your art to all the songs in that album. For songs already on your player, I don't think there's a way, so you would have to delete that song, and reupload it with the album art. Hope this helps.
