I've done some hunting around the tinternet & found some JavaScript code to dynamically load pages into an iframe.
The particular one I used is supposed to also dynamically change the iframes height but I couldn't get this to work but it isn't required anyway. I had to include height: 1000px into the code to force the iframe to be lage enough (it was defaulting to 150px)
Had a bit of bother getting it to work at first but it works fine in the attached xar. Obviously you'll need to change the button links to folders on your computer to view them in action.
