通用破解图片防盗链完美方法!!

现在各大网站的软件不但使用盗链措施,而且图片也防止别人引用。新浪博客、网易相册、百度空间都是这样。

如果直接引用这个图片,显示【该图片来源于百度空间】之类的话。这样他们的流量是有了,但是却苦了我们,令到我们不得不找其他的空间来放图片。转引别人的文章还得把图片先下载下来再传到自己空间里再插入到日志里。真累死人。

今天,我教大家一个可以“破解”这个图片防盗链技术的方法,使用起来很简单,直接将图片上传到【百度空间】、【网易相册】、【新浪博客】之类的空间,然后找到图片的地址,如
http://hiphotos.baidu.com/anhyx/pic/item/ddcf6259053bfb2a2834f09f.jpg]
图片会显示:

然后在图片地址的前面加上
http://www.beihaiw.com/pic.php?url=

即可,最后的网址是为
http://www.beihaiw.com/pic.php?url=http://hiphotos.baidu.com/anhyx/pic/item/ddcf6259053bfb2a2834f09f.jpg

图片会显示:


直接引用这个图片就可以显示了,再也不会显示【该图片来源于哪里哪里】之类的字了

若你有自己的网站,可将以下段代码另存为 tu.asp 存放到你的网站根目录,可破解这种图片盗链,方法同上.
