you want to refresh the part of the page and you using div structure , that means you want to refresh some div entirely.so iframe inside that div.

are you trying to create the animation effect with this, then you should think of some other way for creating animation -
Either this is not working too, though the status bar is blinking continuosly.

<HTML>
<HEAD>
<script LANGUAGE="JavaScript">
<!--
function reloadImg(){
 uniq = new Date();
 uniq = "?"+uniq.getTime();
 newImage = document.images['imgToLoad'].src;
 index = newImage.indexOf("?", 0);
  if(index > 0){
    newImage = newImage.substr(0, index);
  }
 document.images['imgToLoad'].src = newImage+uniq;
 setTimeout('reloadImg()', 3);
}
// -->
</script>
</HEAD>
<body onload="reloadImg()">
<a href="" >
<img src="http://blog.themeforest.net/wp-content/themes/marketplace/images/woods/footer-logo.gif"  height="41" width="127" name="imgToLoad"></a>
</body></html>
