You own Caspervend connect inworld with marketplace. You already require pictures for listing in both. This would allow people to see all purchased items not just clothes.

And by using the RLV feature you could even allow people to dress and undress from a web based system. There are systems already that allow this but you have to painstakingly add every item you purchase. There would need to be a way to choose body/head type, etc. But you already have every UUID ever created in a database each would show with that unique identifier.
