WapcamServer can help you broadcast your webcam by many means: direct access on your computer, FTP upload, redirections...

This method uses a simple HTML image tag pointing to my WapcamServer at home. The short Javascript is here to make the picture refresh automatically.
In order not to consume too much of your bandwidth, or to get on your nerves seeing my face, I've set the refresh rate to 10s and the image queried is 160 pixels width. You can just adapt this script to your need.

 <img style="width: 160px; "
 title="Live Webcam from WapcamServer in Paris"
 alt="WapcamServer is currently down." 
 src="http://demo.wapcamer.com/?width=160"
 name="shot">
 
 <script type="text/javascript">
  function refreshIt() {
    document.images['shot'].src = 'http://demo.wapcamer.com/?width=160&rand=' + Math.random(); 
    setTimeout('refreshIt()',10000); // refresh every 10 sec
  }
 refreshIt();
 </script>


A big thanks to Laurent for coming up with it.

PS: if you see WapcamServer is currently down, then I must be sleeping, come back soon !
