<?php  
define("RelativePath", ".");  
define("PathToCurrentPage", "/");  
define("FileName", "trackdemo.php");  
include(RelativePath . "/Common.php");  
  
  $pid=CCGetParam("pid","");  
      
  $db = new clsDB();  
  $SQL =    "select ProductDemoURL where ProductID=" . $pid ;  
  $db->query($SQL);  
  $db->next_record();  
  $URL = $db->f("ProductDemoURL");  
  
  if ($URL!="") {  
  $SQL =    "UPDATE Products SET ProductDemoDownloads=ProductDemoDownloads+1 where  ProductID=" . $pid ;      
  $db->query($SQL);  
  $db->close();  
header("Location: $URL");  
exit;

that work if you want to download it. To show a picture, you can't hide the url. Any ways, if you hide it, when the user right-click the picter and ask for properties, will see the picture's real url.
