Modifying the OpenDB collection system

[Rogue3]

I'm trying to get a collectors database up and running based on the OpenDB platform. The OpenDB (Open Media Collectors Database) platform was built to collect media such as DVDs. I'm trying to modify it to work with other collectibles. I've got most of it modified, but I'm at the point where some slightly more advanced code editing is due, and I'm not figuring it out. Right now, it is set up where you can import your database from a file such as excel, and it will propogate the database based on what fields you match up. It puts them all on a nice item listing page as seen here:

I'd like to take it a small step further. I'd like to add a column to that layout, on the right side. The column would span the total height of the rows (so, one cell) and would house a large image, likely a fixed size. This image would simply be a database link entry, so it pulls up the image (it already does this for thumbnails associated with the entry). Here is my mock-up of exactly what I'm talking about:

So, i'm thinking that what I would need is a single cell in that location that you can assign a field value to. Then, when I do my import any item (in my case a link of an image) will propogate that field.

 

I'm not sure which files would be edited, but I'd be willing to zip up the whole package and email it to someone. I hope someone can help me out here!
