I'd like to be able to change the name of the existing artwork file as well as create an optimized version. For example, I'd like to have it take the original "cover.jpg", rename it as "cover (original).jpg", and then make the optimized version "cover.jpg". Since I'm also embedding artwork, the current backup option isn't ideal, since I don't need backups of the artwork for every file; I just want to rename the original file as well as give a name to the optimized version in a directory.
