registry list possible?

[LWAA]

I am setting up a photo print store for a local charity using coppermine. Is there a way for a registered user to add existing images to a kind of registry so that other visitors (registered or not) can look at the registry and buy one or two images from it. These images would then be removed from the registry, or have "bought" or something inserted over the thumbnail?
