https://github.com/helloxz/imgurl 源代码是这个，程序自带的伪静态
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]
发现这个用网上的那些规则都无效，
例如
RewriteEngine On
RewriteCond %{HTTP_REFERER} !^$ [NC]
RewriteCond %{HTTP_REFERER} !phpddt.com [NC]
RewriteCond %{HTTP_REFERER} !google.com [NC]
RewriteCond %{HTTP_REFERER} !baidu.com.com [NC]
RewriteCond %{HTTP_REFERER} !feedburner.com [NC]
RewriteCond %{HTTP_REFERER} !feedsky.com [NC]
RewriteRule .*\.(jpg|bmp|png|gif)$
http://www.phpddt.com/ [R,NC,L]
不知道是不是有没有冲突，实际上没有防盗链效果
