Okay. As you can see if you visit my site, the first page is WAY too long. I want to keep all the information in the left table, but I want the visitors to be able to scroll down on that side, with the right staying where it's at. I only want the right side to go down as far as the background picture does.

I know this is possible with frames, but is it possible with tables?

your choice is either frames, iframes, or positioned divs.

Are iframes inline frames? And what's a positioned divider? Sorry for sounding so naive.

Iframe = inline frame yup :)
