Hi Sam.
You can just use the Auctiva URL to put into your code. Is that what you mean?
I know you can make custom templates but don't know how to do it. There are others here that could help with that.
But there's a thread under Templates & Custom Templates with instructions. I've never taken the time to do what it says, or maybe I really could do it.

edit... to get the pic URL, go to manage images and it's in there.
