Walking into this cold: Can Zen do this?

I'm a freelance photographer and I'm ready to start selling prints on-line. I have been approved to accept credit cards but the underwriter is holding up my full acceptance until I have a secure check-out system. Here's what I want to be able to do:

1. Take a bunch of pictures from a shoot (like a horse show), upload them, en masse, to my web site. We're talking probably 500 shots (for example).

2. When the riders go to my main page, there's a link directing them to their particular show. When they click on that link, they see all 500 shots, displayed perhaps 50 per page.

3. The rider clicks on his picture, and that opens up a window showing the print size options and the price for each option. (different prices for different shows?) He selects what he wants, as many pictures as he wants, then when he's done he's ready to check out.

4. A secure check-out system routes his credit card info to Authorize.net.

I have seen a few sample pages and it appears that this is what I'm looking for. But after having perused some of the FAQ sections, I'm not 100% sure. Am I in the right place?

Thanks in advance to all...

Jeff

Zen Cart does all of this. Install and get busy.
:cool:

Can't put it any plainer than that!
