Just installed the latest version and put a set tag in:
[flickr-gallery mode="photoset" photoset="72157605870230826"]
and there is no Lightbox happening - I click an image and it goes to Flickr.
Additionally, there is a 'Next Page' button at the bottom (positioned a bit absurdly) but it doesn't go to the next page of images.
Do I need to install Lightbox separately - didn't find any information about this in the documentation. If so, which Lightbox (a WP plugin or just drop a lightbox dir into the gallery plugin directory)?
Unfinished test site here:
