the directory overview is located at: http://www.example.com/directory rather than http://www.example.com/directory/
Here's the rub.
A link like
href="logo.png" linked from the first one points to
http://www.example.com/logo.png and from the second one points to
http://www.example.com/directory/logo.gif, and that's what breaks a site when people fail to understand that. URLs for folders have a trailing slash for good reason.
