Disambiguation should also apply to image groups on products

[NicolaasHamman]

The disambiguation field on product releases should also be used for the groups of images listed to the side. Currently it's impossible to tell from the List tab which image applies to which release.

Even for regional variations, the game's don't always have different names, and the credits still look the same at a distance. Currently the user has to remember/double-check the order that the game was released in these regions.
