I built a page with navigation and the juice box gallery and quickly discovered that juice box had z-index which forced the splash image on top of my navigation, so I added z-index to my navigation to push it on top of the splash image... but now that i have done this, my navigation appears on top of the portfolio once you click the splash image and it looks horrible.  How can this be fixed?

Visit ...  http://fotorep.me/photographers/steven-white

and see how the navigation works on top of the splash image.

then click the splash image to launch the portfolio and you will see what i mean about my navigation appearing there. 

Now, if I take the z-index out of my navigation then it does not appear in the portfolio (which is what I want), but then it falls behind the splash image.

Please help.
