If you ripped one of your own cd's then the quickest way I found is to select all the songs in that album (shift click the first and last) and then do a "get info". On the right there is a small blank box for album art in the get info screen. Log onto Amazon (any site do but Amazon has most albums and higher res album art) find the album art of the cd and drag the picture to the empty box in get info. Once there it should automatically check mark to show the album art and your done.
