Hi Bo.
An interesting idea for you. How about using the LastFm Audioscrobbler webservices to display the the album cover?
You can find the services here:

Here is the XML for Nickel Creek/This Side
http://ws.audioscrobbler.com/1.0/album/Nickel+Creek/This+Side/info.xml
from which you can extract the cover
