One of the backend changes that came with the release of iTunes 7 is how the app stores album artwork. The days of embedding album artwork in music files are gone, due in part (I assume) to the purchase and integration of CoverFlow, a flashy new way to browse your albums. Artwork is now stored in a new ~/Music/iTunes/Album Artwork/ folder, but what if you want your album artwork embedded in those files? Users can have any number of reasons for wanting this, such as the Growl notifications that Quicksilver creates when iTunes starts playing something new. Those notifications (as I understand it) are incapable of properly display album artwork unless the image is embedded in the file, so iTunes 7 has created a bit of a conundrum with this new organization feature.
Never fear, however, for Doug's AppleScripts for iTunes is yet again to the rescue. Doug has a handy script aptly titled Embed Artwork that can do just what it says: embed the album art back into your files. This should make things easier on Quicksilver + Growl, as well as if you move your media files to a new computer, artwork in tow.
As usual, Doug's scripts are provided for free, but donations for all his hard work are strongly encouraged.
