Convert ZenCart to RomanCart(repost)

This project has two main components. First, I would like to retain part of the database of ZenCart so that the images and product descriptions can be dynamically generated (php). This is possible and there are examples of this discussed on the RC forum. Second, I would like a template with tabs to display details of the products. See example here: [login to view URL] There are actually three carts and I want to create a system in which all of them use the same database and checkout. I think this is actually not complicated at all since all sites are on the same server and RC is the common checkout (or will be). One cart has been converted but it is not using a database for the products. Thank you. More details will be made available to interested coders.
