Provide some code to work off. I'm not trying to be rude, your site looked good, I liked the flash animations.
Frames are probably the best way to handle the situation described, that being said, like I said before, I don't see the point. Research this, google "alternatives to frames in html" or "frames in html". There may be a way using css or javascript although I don't know of it.
The only way I can think of doing this in PHP is with an include statement, but that in itself loads on each page refresh because PHP is compiled at run time.
My apologies if you took my previous post as ignorant, was not my intention.
