.htaccess如何設置防盜鏈某個目錄的圖片

防止排除一些網站盜鏈某個目錄的圖片：

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_REFERER} !^$ [NC]
RewriteCond %{HTTP_REFERER} !google.com [NC]
RewriteCond %{HTTP_REFERER} !baidu.com [NC]
RewriteCond %{HTTP_REFERER} !sogou.com [NC]
RewriteCond %{HTTP_REFERER} !soso.com [NC]
RewriteCond %{HTTP_REFERER} !youdao.com [NC]
RewriteCond %{HTTP_REFERER} !yahoo.cn [NC]
RewriteRule ^uploadfiles/(.*)\.(gif|jpg|png)$ http://www.aoyou0898.com/images/change.gif [L]
