This script will export the artwork of the selected tracks or tracks in the selected playlist as a JPEG image file named folder.jpg to the folder which contains each selected track's file--presumably the track's Album folder. Many third-party music players and systems (Sonos, for example) may look for a "folder.jpg" here to use as display artwork. If multiple album tracks are selected, the script will make sure only one image file per Album is exported.
OS X 10.6 or later only. Previous universal version available at the link below in the "Info" section.
Based on Save Album Art to Album Folder.
