Would something like this work? (ie. could I just put the below into the custom island?)

And would there be any compatibility problems with doing that?

=========================

<script type="text/javascript" language="javascript">

function randomads() {

var ads = new Array();
ads[0] = "image1.gif";
ads[1] = "image2.gif";
ads[2] = "image3.gif";

var adlinks = new Array();
adlinks[0] = "http://www.link1.com";
adlinks[1] = "http://www.link2.com";
adlinks[2] = "http://www.link3.com";

num=Math.floor(Math.random()*ads.length);

document.write("<a href=" +adlinks[num]+ " target=_blank>
<img src=" +ads[num]+ " border=0></a>")
}

</script>





thanks!
