The latest version of my artwork grabbing script for GrowlTunes. This applescript - which is basically a replacement for jackItunesArtwork.scpt - takes the artwork from iTunes, and uses that to set the buddy icon in Adium. If you don't have any artwork associated with your music, then it will just use your default icon in Adium.

I've actually been able to remove a lot of the ugly hacks I had to put in for supporting shared artwork since iTunes has finally made shared tracks first class applescript citizens, meaning that you can use the same method for retrieving shared and embedded artwork in tracks.
