n00b needs a store (or two)

[SEIZMICdesign]

Hi all,

 

Amateur web designer here ( i'm mainly graphic & industrial design) but I now have a couple clients who are asking for online stores. So the internet led me here! This looks to be a pretty awesome option being that it's free and all and pretty powerful.

 

My main question today (the first of many I'm sure) is one of my clients is a photographer. He wants to have the ability for his clients to be able to - in essence - log into their own store. Because his clients own the rights to the images they will be buying, for him and his clients there must be a way to configure his store so that their images cannot be purchased by customers who do not have rights to them. It doesn't really matter what the implementation is, whether a password for each image or set of images or if they have their own store that they essentially log into, I'm just looking fo any sort of solution to this problem. Anyone have any tips or ideas?
