Drupal CMS for starting to sell images and videos as digital downloads


Im really new to Drupal but found that there is Fotomoto -theme (or plugin) which could be compatible with Drupal to establish a ecommerce site for selling images and videos as digital downloads. So that inspired me to ask here what other options there might be to start totally new ecommerce site with those extra features what is needed for selling digital downloads.

As usually same image or video is offered in different sizes with different prices etc.

Anyone here made that kind of site? 

Thanks in advance for any expert advices.
