first do you make the pictue like open a new window by adding the target="blank" like this <A HREF="http://www.dfsdfksd.com/linkus.htm" target="blank">

second use a imaging software and make poportional tumnails of your pictures, and make seperate pages with the large picture on each one.
third, make a page that will has frame on top and one on the bottom
fourth, make the bottom frame have your pictures with links to its large picture page from step 2. Make it so that it will appear on the top frame.
