This will change the image used for a link when the mouse passes over the image. Make sure the images are the same size. In the body part of the script you can use the same image before the mouseover or specify another image for the image on mouseout. The first part of the script goes between the head tags. This is where you specify the before and mouseover images. The second part goes in the body where you want to change images and you can specify the images that shows after mouseout.
