Dynamic Drive- Iframe SSI script II

Hey guys, im having a problem with the above script. Ive managed to get it working fine but say if I load a page into the iframe which is big (height wise) other contents on my page get stretched.

I don't know wether it's because the images are bg images of wether its something to do with locking the height of the tables.

Please feel free to take a look at my site to get a better understanding:


I would like to thank all who take the time to look at my problem and help me out.

Please do NOT attempt to buy a domain name or hosting package as my system is not live and all requests go to a dummy account!
