album art Google Image Search

Although there are lots of other things that do this,
but this one goes straight to a google image search of the album and artist,

you could also put this in /Library/iTunes/Scripts/ so that it will run from the iTunes script menu, you may have to turn it on though.
and lets you select what ever image you want.

1. Select the track (or select the whole album)
2. Run the script
3. Follow the link to the image you want.
4. drag the image to the album art box in iTunes.

tell application "iTunes"
	set theAlbum to album of item 1 of selection as string
	set theartist to artist of item 1 of selection as string
end tell
try
	set thestring to theAlbum & "+" & theartist
	set thestring to do shell script "echo " & thestring & " | sed 's/ /+/g'"
end try

set theUrl to "http://images.google.com/images?client=safari&rls=en&q=" & thestring
