<html>
<head>
<script type="text/javascript">
var firstJan = Math.floor((new Date().setFullYear(new Date().getFullYear(),0,1))/86400000);
var today = Math.ceil((new Date().getTime())/86400000);
var dayOfYear = today-firstJan;
var bgdImage;
if((dayOfYear+'').length == 1)
bgdImage = '00'+dayOfYear+'.jpg';
else if((dayOfYear+'').length == 2)
bgdImage = '0'+dayOfYear+'.jpg';
else
bgdImage = dayOfYear+'.jpg';
document.getElementById('bla').src = "bgdImage";
