Yes, seems to refresh the image okay in Internet Explorer, but not in Firefox.

Searching around, this appears to be a common problem.  There's Javascript around to refersh images, I'll try those later.

Your shot just updated to 14:24 at 14:37

Maybe there's something going on in the background here with the free host?  I works a treat using the Demon ISP.

This Javascript seems to force an image refresh.

<html>
<head>
<title>Radarbox at Portmahomack</title>
<meta http-equiv="refresh" content="60; URL=http://www.tarbat.gofreeserve.com/radarbox.htm">
<meta http-equiv="expires" content="0">
<script type="text/JavaScript">
<!--
function timedRefresh(timeoutPeriod) {
   setTimeout("location.reload(true);",timeoutPeriod);
}
//   -->
</script>
</head>
<body onload="JavaScript:timedRefresh(60000);">
<iframe width="565" height="601" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://www.tarbat.gofreeserve.com/shot/RadarBoxScreenShot.gif?xx"></iframe>

I've saved that and I'll try it later - thanks tarbat.

Going to be up in your part of the world next week - got a briefing to do at EGQS.  Lets hope I don't get caught in the snow like last time!  Looks like it's raining now though :-)

Allocator, hope the weather's better than it is now - gales force winds and rain :(

I've been reading various forums about image refreshes, and this seems to be a Firefox problem.  Using the following HTML, I can get the image to refresh every 60 seconds in Internet Explorer, but not in Firefox.  http://www.tarbat.gofreeserve.com/radarbox.htm

Has anyone found how to force Firefox to not use the cached image, and instead download the new image?

<html>
<head>
<title>Radarbox at Portmahomack</title>
<META HTTP-EQUIV="refresh" content="60">
<META HTTP-EQUIV="expires" content="0">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-store">
<META HTTP-EQUIV="Pragma-directive" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Directive" CONTENT="no-cache">
<body>
<iframe width="565" height="601" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://www.tarbat.gofreeserve.com/shot/RadarBoxScreenShot.gif?<%=(new java.util.Date()).getTime()%>"></iframe>

Thanks Andy.  Yes, it just seems to be a Firefox problem.  So, does anyone know how to force Firefox to NOT use the cached image on the user's PC?

Hi tarbat,

I'd just like to say thanks for the code above. I've now got my screen displaying on my website successfully.
