How do I...Exclude a Directory in mod rewrite rules?

Edit mod_rewrite rules

Edit your Deki Wiki apache configuration (on Debian this is /etc/apache2/sites-available/deki).  Before or after this line:

RewriteCond %{REQUEST_URI} !/(@api|editor|skins|config|@gui)/

Add a line like this:

RewriteCond %{REQUEST_URI} !^/(photos|photos/.*)$

/etc/init.d/apache2 reload
