OS X 10.8 or later only. This script will export the artwork of the selected tracks (or the tracks in a selected playlist) as an image file to the folder which contains each selected track's file--presumably the track's Album folder--or a single user-selected folder. If multiple album tracks are selected, the script will make sure only one artwork file per Album is exported.
Also see Save Album Art as folder.jpg.
The image output settings will be saved between uses.
