Thanks but my problem hasn't been with music that I've ripped and encoded myself from my CD's. The album art for that shows up fine on my Axim.
But I think I've found the problem. Perhaps the album art from my downloaded copies are embedded within the files. I found the issue in some FAQ's on the Windows Media for Mobile website.
