This script will delete all the artwork from every track in the selected iPod, thus freeing up some space.
Although you could easily select every track in the iPod library, select Get Info, OK a multiple edit, and check-mark the empty artwork panel, the process of removing artwork in this manner would tie-up iTunes and iPod until the artwork has been removed. This script will work in the background and allow you to continue using iTunes.
(Note: In order to launch this PowerPC-era script on an Intel machine, it must first be opened and then saved using Script Editor (AppleScript Editor pre-OS X 10.0) which is located in your /Applications/Utilities/ folder. More information is here.)
