Apache服务器下防止图片盗链的办法,

先解释一下图片防盗链和转向:

  图片防盗链有什么用?

  防止其它网站盗用你的图片,浪费你宝贵的流量。

  图片转向有什么用?

  如果你的网站以图片为主,哪天发现月底没到流量就快用光了,那就可以利用图片转向,在不修改网页的前提下,把图片下载请求转向到其它空间(比如试用主机),临时过渡。

  下面开始讲解,比如你的图片都在img目录下,那就在该目录下放一个名为 .htaccess 的文件,内容如下:

  RewriteEngine on

  RewriteCond %{HTTP_REFERER} !^$ [NC]

  RewriteCond %{HTTP_REFERER} !simcole.cn [NC]

  RewriteCond %{HTTP_REFERER} !zhuaxia.com [NC]

  RewriteCond %{HTTP_REFERER} !google.com [NC]

  RewriteCond %{HTTP_REFERER} !baidu.com [NC]

  RewriteCond %{HTTP_REFERER} !bloglines.com [NC]

  RewriteRule .(jpg|gif|png|bmp|swf|jpeg) /image/replace.gif [R,NC,L]

  RewriteRule ^(.*)$ http://image.simcole.cn/image/$1 [L]

Copy after login

  大概解释下:

  RewriteCond %{HTTP_REFERER} !^$ [NC]

  RewriteCond %{HTTP_REFERER} !simcole.cn [NC]

  RewriteCond %{HTTP_REFERER} !zhuaxia.com [NC]

  RewriteCond %{HTTP_REFERER} !google.com [NC]

  RewriteCond %{HTTP_REFERER} !baidu.com [NC]

  RewriteCond %{HTTP_REFERER} !bloglines.com [NC]

Copy after login

  这部分是判断是否盗链,如果以上条件都成立(即访问图片的请求,既不是直接输入网址,也不是来自simcole.cn,也不是来自zhuaxia.com,也不是来自google.com,也不是来自baidu.com,也不是来自bloglines.com 的话),就执行下列转向:

  

RewriteRule .(jpg|gif|png|bmp|swf|jpeg) /image/replace.gif [R,NC,L]
Copy after login

  意思是让所有盗链 img 目录下 jpg、gif、png、bmp、swf、jpeg 文件的网页,显示的图片都用 image 目录下的 replace.gif 图片替换掉。注意替换显示的图片不要放在设置防盗链的 img 目录下。如果照上面的规则判断出图片请求不是盗链的,就执行以下转向:

  RewriteRule ^(.*)$ http://image.simcole.cn/image/$1 [L]

Copy after login

  意思是对 img 目录下所有的请求都转向到目标服务器,比如有个图片原来的 url 是 http://www.bebecn.com/img/girl.jpg ,现在就会转到 http://image.bebecn.com/image/girl.jpg 去。当然了你得先把原服务器 img 目录下的文件统统拷贝到临时服务器的 image 目录下,转向才会真正可用。起到的效果就是把原服务器图片下载所占用的流量统统省下,让临时服务器来承受了.
