  com_message_pump(4000);
}
$im = imagegrabwindow($handle, 0);
$ie->Quit();
$file="public/images/".time()."iesnap.png";
imagepng($im,$file);
//--------------------
$browser = new COM("InternetExplorer.Application");
$handle = $browser->HWND;
$browser->Visible = true;
$browser->FullScreen = true;
$browser->Navigate($webaddress);
while ($browser->Busy) {
  com_message_pump(4000);
}
$im = imagegrabwindow($handle, 0);
$browser->Quit();
//opendir("public/images/");
$new_img=imagecreatetruecolor("206","132");
$file="public/images/".time()."ie.png";
imagecopyresampled($new_img,$im,0,0,206,132,206,142,1024,768);
imagepng($new_img ,$file);
imagedestroy($new_img);
