here is a post i wrote a while back on this topic. Since then, I have also learned that you need to look at how itunes stores the album art. by default i stores it by album and does not copy it to each individual music track, unless you purchased it from apple, in which case it will be included for each track. you can manually add the album art pics to each track or use a program like tune up to help you.
