Safari Javascript Image Reload Issue

I need to get an image to refresh itself via JavaScript instead of reloading the page.

This code:

<!DOCTYPE html>

<html>
<head>
<script type="text/javascript" language="JavaScript">
refreshImage = function()
{
document.getElementById('cam').setAttribute('src', 'http://192.168.1.81/image.jpg?width=2560&height=1920&denom=3');
document.getElementById('cam2').setAttribute('src', 'http://192.168.1.81/image.jpg?width=2560&height=1920&denom=3');
document.getElementById('cam2').reload();
document.getElementById('cam1').reload();

}
</script>

</head>
<body>

<center><img src="http://192.168.1.81/image.jpg?width=2560&height=1920&denom=3" id="cam" alt="Image" width="640" height="480" onload="setInterval(refreshImage, 1);"></center><br>
<center><img src="http://192.168.1.81/image.jpg?width=2560&height=1920&denom=3" id="cam2" alt="Image1" width="320" height="240" onload="setInterval(refreshImage, 1);"></center>

</body>
</html>

Works everywhere except for Safari, which I need it to work in.
What could I possible be doing wrong?
It loads the initial image but won't reload.

every time you load the image, you start an interval. That interval is every millisecond - no way can the cam load that fast and you make interval after interval.

Try this code
<!DOCTYPE html>

<html>
<head>
<script type="text/javascript" language="JavaScript">
var tId;
window.onload=function() {
  tId=setInterval(function() {  
    document.getElementById('cam').setAttribute('src', 'http://192.168.1.81/image.jpg?width=2560&height=1920&denom=3&rnd='+new Date().getTime());
    document.getElementById('cam2').setAttribute('src', 'http://192.168.1.81/image.jpg?width=2560&height=1920&denom=3&rnd='+new Date().getTime());
  },1000); // milliseconds so I would suggest 3000 or so
}

</script>

</head>
<body>

<center><img src="http://192.168.1.81/image.jpg?width=2560&height=1920&denom=3" id="cam" alt="Image" width="640" height="480" /></center><br>
<center><img src="http://192.168.1.81/image.jpg?width=2560&height=1920&denom=3" id="cam2" alt="Image1" width="320" height="240" /></center>

That worked wonderfully, I was actually able to tweak it to around 500 and it works great on the iPad.  Thanks for the quick response I was going crack!.
