it does reload the page... but it's all CSS and no images, so it reloads exteremly fast since after the initial download, the CSS is on the client side and doesn't need to be re-downloaded. It's in site design, nothing really PHP related.

EDIT
Excuse me, it's 3 images... all extremely small in size.
2 corner images, and the top header image
The rest is done via CSS/Tables....
