I have a layout that consists of a picture in the top-center of the page and underneath of it i have some links. When someone clicks on one of the links, it will open up in the window below. So i was just wondering if there's a way to make that top picture to change everytime I clicked on a link. THanks.

You can put the image(s) as separate pages in an iframe and then use a code to change two iframes at once http://www.lissaexplains.com/forum/showthread.php?t=40793

Or do you just want it to change on mouseover?

oh ok thanks..i'll look into that thread.
