guys here is the link of the page: http://nits4u.110mb.com/gallery.html

as you can see, it takes too long to see the complete images in the gallery. Also takes alot of time on slow connections.
So i want to divide the pictures in two sections that display in two pages. But i want only the main content to be change not whole of the page i.e. bg image, header etc. I am thinking of giving "next" & "prev" links at top or bottom of the page. Hope you understand.

Thank You!!
