I believe member_8880 makes a very good point. There should be no confusion about what the buyer is getting (which pics of variations can create), and "choice" listings are specifically not allowed by ebay. Ebay does not allow multiple items on a listing unless they are either (1) identical items sold in a dutch auction, or (2)identical or similar items sold as a lot.

Technically you can accomplish what you want by inserting the photos into the description manually. You can even have captions. This thread explains how:
