WebCam setup

I have an application that sends a new .jpg file to my server every 15 seconds (from my camera).  I tried to use:
<meta HTTP-EQUIV="Refresh" CONTENT="15; URL=http://www.zzz.com/webcam.htm">

to make the page refresh every 15 seconds but it doesn't update the picture.  The html is simply a page with a jpg picture.  How can I make the page continue to update when I send a new picture?

Bu using an image with an additoon ? + randomnumber

ie. with javascript it'd look like:

<script language=javascript>
<!--
var MyImg = new Image();
    function UpdatePic()
    {
       MyImg.src="http://www.mysite.com/image?"+ Math.random();
       document.MyWebcam.src = MyImg.src;    
       setTimeout("UpdatePic()", 150);
    }

setTimeout("UpdatePic()", 150);
//-->
</script>

<img id=MyWebcam>

or something like that. This way you don't even have to use the META refresh tag.

Hi!
We have similar page with web-camera.
Also we use a refresh-method for clients with low speed of connection to the Internet.

Try to make so:

=======================================

<META HTTP-EQUIV="EXPIRES" CONTENT="0">
<meta http-equiv="Refresh" content="15">
<meta http-equiv="Pragma" content="no-cache">
</head>

<body>
<img src="http://www.zzz.com/webcam.jpg" width=* height =* >...

=======================================

Differently go to http://weather.tomsk.net, click on an icon with the camera and look a refresh-method.

Good luck!
Excuse for my bad English.
