Webcam refresh script...

[OpalCat]

I was given this bit of code:

<img src="current.jpg" name="refresh" width="306" height="408"> 
      <script language="JavaScript" type="text/javascript"> 
      <!-- 
      image = "current.jpg" //name of the image 
      function Reload() { 
      tmp = new Date(); 
      tmp = "?"+tmp.getTime() 
      document.images["refresh"].src = image+tmp 
      setTimeout("Reload()",1000) 
      } 
      Reload(); 

      // --> 
      </script>

to refresh a webcam image. I want to know what it means--how often is it set to refresh? I don't know javascript so I can't tell. Is it set to refresh whenever the image is new? or what? I would like to move away from my meta-refresh page-in-an-iframe method of refreshing my webcam if I can. My cam uploads a new image every 5 seconds. I need code that would allow the new image to be seen. Will this code do it? I tried it and it doesn't seem to refresh that often. So what does it do, and can it be tweaked?

[Occam's Razor]

The refresh interval is set here:

setTimeout("Reload()",[ICODE]1000[/ICODE])

That is in "ms" and not regular seconds so divide the number by 1000 to get seconds.

Basically, it refreshes once per second. To get a 5-second refresh just change 1000 to 5000.
