This script will re-embed artwork downloaded from the iTunes Store into the files of the selected tracks.
Also see Re-Embed Artwork.
NOTE: this script cannot handle processing more than about an album's worth of tracks per launch due to the way iTunes manages the graphics data.
Note: (August 2014) Not sure what the issue is but results are inconsistent with modern versions of iTunes.
