Only display nav if there is more than one image

[Ryuno-Ki]

To use your module as replacement for jQuery prettyPhoto (which is GPL v2-licensed) I needed to make some adjustments.

To me, the lightbox nav is only required, if I load more than one image into the modal (which I don't).
So I added data-ng-if="Lightbox.images.length > 1" to the .btn-group of .lightbox-nav.

Maybe you want to adjust your template as well ;-)

Fixed, sorry for the delay.
