Code to display two images help!

[MarkFoster]

If I use this code:

<SCRIPT LANGUAGE="JavaScript">
 
<!-- Begin Random Logo In Header Script
 
var theImages = new Array() // do not change this
 
<!-- Edit the url images to match yours
theImages[0] = 'images/statusicon/forum_old.gif'
theImages[1] = 'images/statusicon/forum_new.gif'
 
 
 
var j = 0
var p = theImages.length;
var preBuffer = new Array()
for (i = 0; i < p; i++){
preBuffer[i] = new Image()
preBuffer[i].src = theImages[i]
}
var whichImage = Math.round(Math.random()*(p-1));
function showImage(){
document.write('<td align="$stylevar[left]"><a href="index.php"><img src="'+theImages[whichImage]+'" border="0" alt="$vboptions[bbtitle]" /></a></div>');
}
 
// End -->
</script>

How will I be able to use two images at one "theImages[0] = 'images/statusicon/forum_old.gif'" ?

Thanks.
