I have designed a website that sells images/stock photography which are uploaded by the users. Once a user uploads an image, it needs to be approved by admin before appearing in the database for sale.

I have created the design in two sections, the main website and the admin section.

Main website is where a user search for images, creates account, modify information, upload images, buy images, add to favorite list, add to shopping cart, request a payout.

The admin section is to manage users/members, add delete information, send newsletter, approve/decline images uploaded by users, maintain account, authorize payments etc.

This is the basic of what i am looking for. It will also require a secure payment gateway, so will need suggestions on that.

Cheers!
