The DK.ASPNET progress indicator (the hourglass) can be easily modified by adding JavaScript code to the end of the
.aspx page.
</body>
<script type="text/javascript">
function getHourglass(id){
return "<td valign='middle' align='center'><img src='hourglass.gif'/></td>";
}
</script>
</html>
Only the yellow highlighted text can be safely modified. In particular, persisting of img tag is crucial.
