[Plugin: NextGEN Gallery] Help, anyone know how to open gallery in a lightbox with custom menu butto

I have a menu button called photography, when clicked I want the gallery to open in a lightbox over my site (regardless of what page user is on)
I have been looking everywhere for this and can’t seem to find one that works.

Please need help with this, I don’t want the gallery on a page with thumbs that are clicked, it has to go directly into the lightbox.
Something like this is perfect, hit portfolio and works just like I am wanting to acheive.
