Hello everyone!

I got this:

<center><script type="text/javascript">
var imgs1 = new Array("http://img687.imageshack.us/img687/4438/kamslide3.jpg","http://img143.imageshack.us/img143/5968/kamslide2.jpg","http://img696.imageshack.us/img696/7066/kamslide1.jpg");

var alt1 = new Array();
var currentAd1 = 0;
var imgCt1 = 3;
function cycle1() {
if (currentAd1 == imgCt1) {
currentAd1 = 0;
}
var banner1 = document.getElementById('adBanner1');
var link1 = document.getElementById('adLink1');
banner1.src=imgs1[currentAd1]
banner1.alt=alt1[currentAd1]
currentAd1++;
}
window.setInterval("cycle1()",7000);
</script>
<img src="http://img687.imageshack.us/img687/4438/kamslide3.jpg" id="adBanner1" border="0" width="861" height="267" /></center>

How can I make the image fade??
