Position: absolute problem for gallery image window in dynamic php page

I have an image gallery I found at > http://monc.se/kitchen/80/lightweight-image-gallery-with-thumbnails. Code for the whole thing I've set below.The main image display window is set w/ a fixed position w/ this CSS code:

[CODE]#jgal li img { position: absolute; top: 20px; left: 220px; display: none; }[/CODE]

I want to use it on dynamic php pages that have constantly changing content. I cannot w/ the fixed position. I need it to float correctly to the right of the thumb sidebar images. I've set it into my .tpl pages & it works well w/ no apparant css conflicts. But the main window is still fixed while the thumbs show wherever I place their code. Any ideas how I can float it all as a unit? Example working not in the php page, just regular HTML > http://www.easysavannah.com/gallerytest4.html
The large image window on the right is fixed in position in the page. I need it to have a fixed position right where it's at now in relationship to the sidebar on the left. No matter where I place it's code. Thanks, Gene
