I'm pretty sure it's all photographed and stored wether u sign up or not.

Not sure of the down votes, but I have the same assumption. Actually, my guess is that they were doing this first, and then someone said, "Hey, we could charge people for this as a service, and then that would offset some of the costs." Of course that person would not have received a raise or bonus for the idea though.

They do not, however, charge for the service.
