Does anyone know of a script that can be used to sell stock photography - while securing pictures from download.

I am a photographer that would like to sell my photo's from my website.
I installed the Coppermine Gallery, but it is just a photo album more or less.
Then I downloaded OsCommerce, nice, but the end user can download the product image.
I want to have a shopping cart, and the restriction emposed upon download pictures directly from the site.
