If you have a very large pride, it can be hard to keep track of all your lionesses and cubs. Sometimes you have two lionesses with similar names who you keep mixing up. Or maybe you're looking to sell a particular cub to someone, but you have 15 cubs marked "FOR SALE" and you can't remember which was the one with the special markings...

I propose that a thumbnail feature be added to the Den page that shows a small preview image of each lion, above or somewhere near the name. This can be toggled off for users who prefer not to have it enabled for whatever reason.
