Small javascript job(repost)

I have a javascript that allows users to view small portions of a map that I sell. Go to this page and drag your cursor over the photo of the map: [login to view URL] What I want is for the viewing window on the zoomed in part to be a circle and look more like you are viewing it through a magnifying glass, like with beveled edges. I also want to be able to place something besides this on the page. As it is now, I can't get anything else to show up. Just a header and a footer where I can use a simple include file for the header and the footer, having the image as the body of the page, would be fine. I am going to do with with all of the maps on this site and I know how to create the coordinates of the image and paste them in to the script. The current script seems kind of jumpy. If it could operate more smoothly that would be good too.
