code:

var url  = 'http://www.google.co.uk/intl/en_uk/images/logo.gif';
var http = new ActiveXObject('Microsoft.XMLHTTP');
http.open('HEAD', url, true);
http.onreadystatechange = function(){
   if(http.readyState == 4){
      if(http.status == 200){
         Debug.Trace(http.getResponseHeader('Content-Length'));
      }
   }
}
http.send(null);

Doesn't always work though, depends if the header is sent (only seems to be sent on static files). No other way of getting the size before downloading that I know of...
