推荐答案

这将显示一个固定的形象，只要它的热链接。 （该图像可能有盗链在不允许的消息......）

This will show a fixed image whenever its hotlinked. (That image may have a message that Hotlinking in not allowed...)

RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mydomain\.com [NC]
RewriteRule .*\.(jpe?g|gif|bmp|png)$ /images/nohotlink.jpg [L]

它检查Refererr没有什么，引用者是不匹配的mydomain然后将其与图像响应 nohotlink.jpg 。
