PHP generates web snapshots without COM or extensions.

 
<?php 
$url = 'www.baidu.com'; //Grab baidu
echo snapshot($url); //The output is the image address
echo snapshot($url, './baidu.png'); //Save the image to the local baidu.png, output content picture size
 
function snapshot($site, $path = '', $dealy = 0) 
{ 
$url = 'http://ppt.cc/yo2/catch.php'; 
$query = 'url=' . $site . '&delay=' . $dealy . '&rnd=' . mt_rand(1, 9); 
$ch = curl_init($url); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $query); 
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$data = curl_exec($ch); 
curl_close($ch); 
if (strlen($data) != 32) { 
exit(' Invalid url '); 
} 
$file = $data{0} . '/' . $data{1} . '/' . $data{2} . '/'; 
$file = 'http://cache.ppt.cc/' . $file . 'src_' . $data . '.png'; 
if (!empty($path)) {
