I would just use an XmlHttp hit the first time, pattern match "uf*.gif",
and then a second request for the image. This is some code I've migrated
from one of my homebrew samples. Save it as a new htm file:

'// ========================================================
<html>
<head>

<title> Test </title>

<script language="javascript">

var ksRoot = "http://www.userfriendly.org/cartoons/";;

function showImage( sImage ){
        var s = '';
        try{
        //attempt to obtain the content
          var sUrl  = "http://ars.userfriendly.org/cartoons/?id="; +
sImage;
          var xmlHttp = new ActiveXObject("Microsoft.XmlHttp");
          xmlHttp.open("GET", sUrl, false);
          xmlHttp.send();

        //get the response content from the remote site
          var sBody = xmlHttp.responseText;
          var rx = /(\/archives\/[0-9a-zA-Z]+\/uf[\d]+\.gif)/g;
//3456789`123456789`123456789`123456789`123456789`123456789`123456789`
          var r; var i = 0;
          if ((r = rx.exec(sBody)) != null){
            sParsed = r[1];
          }
          sParsed = sParsed.substr(1);

        }catch(e){
          alert( "It didn't work!" + "\n" + e.number + "::" +
e.description);
        }

        var o = document.getElementById('testimg');
        o.src = ksRoot + sParsed;
}

</script>

</head>
<body>

<img src="http://12pointdesign.com/stock/images/ra-button.gif";
id="testimg" /> <br />

<a onclick="javascript:showImage('20060120');"> 20060120 </a> <br />
<a onclick="javascript:showImage('20060121');"> 20060121 </a> <br />
<a onclick="javascript:showImage('20060122');"> 20060122 </a> <br />
<a onclick="javascript:showImage('20060123');"> 20060123 </a> <br />

</body>
