用户直接修改apache中的.htaccess文件即可
RewriteEngine On
#Replace ?mysite.com/ with your blog url
RewriteCond %{HTTP_REFERER} !^http://(.+.)?mysite.com/ [NC]
RewriteCond %{HTTP_REFERER} !^$
#Replace /images/nohotlink.jpg with your "don't hotlink" image url
RewriteRule .*.(jpe?g|gif|bmp|png)$ /images/nohotlink.jpg [L]
注：替换mysite为自己的网址和/images/notlink.jpg为自己定制的防盗链声明图片。
