ecommerce: upload multiple images and sell them separately

Hi,

I would like to set-up a site where the user can buy images.
The problem is, I would like to upload hundreds of images and sell them, but I cant upload each image separately as product ( too long).

So, I would like a plugin able to upload a “pack” of images ( maybe with a “category” for each pack ) and sell them.

Does anybody knows a plugin able to do this?
I tried MarketPress Lite, whic is a GREAT plugin, but does not have this option…
