Hi all.

I want to create a digital photo store where users upload the photos themselves and they can be purchased from a store.
I've set up a ZC 1.3.8a with Gallery 2 integration and works wonders, a great module. So far, so good. But I can't figure out how to allow buyers to directly download the purchased pictures in a zip file instead of ordering prints or such.
Is there any module/feature/etc that can do this?
Searched the web and forums about this, but download is bound to the store admin upping the pictures and, in this particular case, I want the photo authors to up them themselves by using the Gallery 2 application, and the customers browsing thru Gallery 2, too.
Any help/pointers/advice will be appreciated.
Thanks in advance.
