RewriteRule

Hello -

I have WPMU configured to use subdomains (name.domain.com) and have used the .htaccess as recommended:

RewriteEngine On
RewriteBase /

#uploaded files
RewriteRule ^(.*/)?files/$ index.php [L]
RewriteCond %{REQUEST_URI} !.*wp-content/plugins.*
RewriteRule ^(.*/)?files/(.*) wp-content/blogs.php?file=$2 [L]
RewriteRule ^(.*/)?avatar/(.*) wp-content/avatar.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteCond %{REQUEST_URI} ^.*/wp-admin$
RewriteRule ^(.+)$ $1/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>

Now, I've installed photo software in a subdirectory of my html_root/photo

I want to add a rule that says all should behave as it currently does but if you access a url with /photo in it, to then just pass it through to that directory. so in otherwords, if someone goes to name.domain.com they get their blog, but if they go to domain.com/photo, then they access the index.php in that directory.

Any clues?

Thanks
