Good day!

What do you think about the idea of using CubeCart, OS Commerce or Zen Cart to build an online shopping mall that sells photos?

Basically what I need is something similar to a shopping cart where user will need to register, add the photos to the cart and also checkout to payment gateway.

In addition to these, the system shall be able to allow uploads of high resolution photos and users will be able to view full sized photos other than thumbnails. Once the payment is made, a download link will be shown.

Will any of the above e-commerce softwares do the job? I am quite new on this area so any advice and suggestion will be much appreaciated! :)

Instead of faffing about with OS scripts why don't you just use a script that's built for the job, something like http://www.ktools.net/
