I see the navagation links in vBulletin navbar when on the gallery page.
AdminCP => vBa Gallery => Modify Settings => Header Replacements
Here you may enter a list of filenames that may appear in your header that should be prefixed with your Forum's URL.
EX:
memberlist.php
usercp.php
register.php
faq.php
calendar.php
search.php
login.php
forumdisplay.php
profile.php
private.php
subscription.php
member.php
online.php
BTW: nice style, good header
