How to bypass image hotlink protection in PHP

<script>window.sc="<img src='http://cdn.jbxue.com//uploads/2011/06/1309476244-elicium-rai-01-528x351.jpg?" +Math.random()+"'>";</script>

2. Curl method usage:

3. PHP header sends various types of files for download File name: showpic.php

 $url = $_GET["url"];
 //$url = str_replace("http://","http://",$url);
 $dir = pathinfo($url);
 $host = $dir['dirname'];
 $refer = $host.'/';

 $ch = curl_init($url);
 curl_setopt ($ch, CURLOPT_REFERER, $ refer);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);//Activation can modify the page
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
 $ data = curl_exec($ch);
 curl_close($ch);

 $ext = strtolower(substr(strrchr($img,'.'),1,10));
 $types = array(
 'gif' =>'image/gif',
 'jpeg'=>'image/jpeg',
 'jpg'=>'image/jpeg',
 'jpe'=>'image/jpeg',
 ' png'=>'image/png',
 );
 $type = $types[$ext] ? $types[$ext] : 'image/jpeg';
 header("Content-type: ".$type ; !
