本文实例讲述了php实现的网络相册图片防盗链完美破解方法。分享给大家供大家参考。具体如下：
网络相册图片防盗链破解程序 - PHP版 这个防盗链破解版可以完美破解当下比较流行的: 百度相册,网易相册,360我喜欢等网站图片. 还可以实现简单的图片防盗链. 因为这个类是先进行获取远程图片, 然后再把图片发送到客户端,所以,算是进行了两次流量的传送.因此,会浪费空间流量,接下来,会开发缓存功能,这样可以实现节约流量!

/**
* 网络相册图片防盗链破解程序 - PHP版
*
* 使用方法：
*
* http://yourdomain/url.php?url=http://hiphotos.baidu.com/verdana/pic/item/baidupicture.jpg&referer=
* 其中url是指需要破解的图片URL,而referer是为了兼容一些不需要设置来路域名才能显示的相册,例如360我喜欢网,必须设置来路为空才能正常浏览. 所以,此时应该设置referer为1
