refresh image source only

I would like to refresh the following code only, every 5 seconds.

The code sends a variable to a php script. user=atodd is the variable and must stay in the code.

<img src="is_online/is_online.php?user=atodd"/>

Any help would be greatly appreciated.

<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<script>
function calling()
{
timer=setTimeout("imgrefresh()",5000)
}
function imgrefresh()
{
g.innerHTML="<img src='one.jpg' width=100 height=300>"
clearTimeout(timer)
}
</script>
</HEAD>

<BODY onload="calling()">
<div id="g"></div>
</BODY>
</HTML>

This will load the image after 5 sec. If you want continous loading of the image, after the line clearTimeout(timer), write calling(). This will again call imgrefresh after every 5 seconds. Take care if you call calling() continously, this may hang your system.
