PHP implementation of the network album Picture anti-theft chain Perfect crack method _php skills

This article describes the implementation of the PHP network photo album anti-theft chain Perfect Way to crack. Share to everyone for your reference. Specifically as follows:

Network photo album anti-theft chain crack Procedures-PHP version of this anti-theft chain cracked version can be perfect to crack the current more popular: Baidu albums, NetEase albums, 360 I like the site pictures. can also achieve a simple picture anti-theft chain. Because this class is to get the remote image first, and then send the picture to the client, so that is carried out two traffic flow. Therefore, will waste space flow, next, will develop the caching function, this can realize saves the traffic!

<?php/** * Network photo album anti-theft chain crack Procedures-PHP version * * Use method: * * * http://yourdomain/url.php?url=http://hiphotos. baidu.com/verdana/pic/item/baidupicture.jpg&referer= * Where the URL refers to the need to crack the picture URL, and Referer is to be compatible with some do not need to set the routing name to display the album, For example 360 I like the net, must set the antecedents to be empty to be able to browse normally.
