#2 Allow 'Nested' Highlighted Pictures

I like to have multiple nested albums- I have too many
photos to place in simple albums.

The way nGallery works right now, I cannot "highlight"
an album. For example, I have a gallery called "Hikes"
with no images in it. Within the "Hikes" gallery I have
multiple sub-galleries.

Without loading a dummy image into the parent Hikes
gallery, I cannot show a highlighted image for the base
album. The ability to highlight a sub-album and show
the sub-albums highlighted image as the parent album's
highlighted image would be very usefull.
