Image Refresh in FF Yes in IE No

[Robert_2006]

I'm aware of how the cache can prevent images from updating, this is over come by appending random characters to the image. That's what I've done below. Yet it doesn't seem to function in IE. I need the value in id to be passed to verify-image.php. I have tried swapping the placement of ID and rnum but that had no effect. Do you guys have any ideas?

function reloadImage()
{
   var id = document.form1.id_check.value;
   var rnum = parseInt(Math.random()*10);
   img = document.getElementById('Captcha');
   img.src = "./includes/verify-image.php?"+rnum+"&id="+id;

}

I'll settle for ideas or thoughts if you don't have an answer.

Why did you use parseInt()?

I prefer using the following to generate a always changing string for that purpose.

(new Date()).getTime()

The code came from an excististing chunk of code, I'm not a javascript guy if you can tell

Changing it though yeilds the same results.

I'll buy anyone lunch (via paypal) if you have the solution...

Someone must have had the same issue before. Any thoughts?
