I'm sorry if this has already been suggested, my search did not find it.

I would like to see an "Alternate Front Image" and/or "Alternate Back Image" or whatever option. This idea came as a result of seeing the submissions lately of Pan's Labyrinth: 2-Disc Platinum Series.
The cover is hard to scan so the inside cover without the slip cover is being submitted as an alternative.

With this option the best slip cover could be submitted with this as an addition. I suppose the inside cover would have to merit significant change and or information, or not. I also don't know if a flag or something could be added as to not have "empty" tabs on DVD's without slip covers or if this even matters. It would also have a check mark option when updating like it is now.

A further suggestion could be to be able to rename the tab so a user could add the inside scan of a booklet style slip cover or DVD instert of some merit and call it what they wanted. Just to personalize.

I think maybe I'm starting to over kill this idea so I'll propose it as it is.
