All NextGen Galleries in Lightbox -  Loads all galleries on a single page via lightbox instead of going to the actual gallery page.  Just add the files appropriately then use this shortcode `[album id=0 template=lightbox]`  id of 0 will force NGG to load all galleries.

What I did instead however was set the default compact album to use the lightbox theme across the site.  I haven't tested if this will cause an issue when using template=lightbox or not.
