CentOS - Aug 2009 - httpd .htaccess rewrite for images

Hello,
	I'm running httpd on a Centos 5.3 machine. I'm trying to use
.htaccess to disable direct linking to site images. I've got the following
rewrite rule, the domain is test.example.com which is at
/var/www/test.example.com under which is a directory called images.

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(test\.)?example.com/.*$ [NC]
RewriteRule \.(jpg|gif)$ - [F]

In my httpd virtual host directive i have:

alias /images "/var/www/test.example.com/images"
<Directory "/var/www/test.example.com/images">
Options None
AllowOverride None
order allow,deny
Allow from all
</Directory>

Comments appreciated.
Thanks.
Dave.

Assume you mean that the rewrites are ignored.  Note that "AllowOverride
None" tells apache to completely ignore .htaccess files.
Either move your rewrite rules into the vhost container or consider
"AllowOverride FileInfo".
