Basic Mouseover Function - by Michael Tangen

1. Place the following code between the <head> </head> tags.
Be sure to modify the variable imagePath to point to the relative or absolute path
to where your images are stored.
<script language="javascript">
<!--
function imageSwap(imageID, imageName) {
var imagePath = "/images/";
document.getElementById(imageID).src = imagePath + imageName;
}
//-->
</script>
2. Ensure your image has a UNIQUE id value (id="valuehere") and be sure to specify
the image name for both the mouseover image and the mouseout image. Both images
should be the SAME SIZE for optimal performance.
<a href="#"><img src="images/off.gif" id="item" width="200" height="75" border="0"
onMouseOver="imageSwap(this.id,'over.gif')" onMouseOut="imageSwap(this.id,'off.gif')"/></a>
