Using NextGEN along with with "Effects for NextGEN" plugin for it's Lightbox effect.
Embedding the gallery on homepage and hovering over the 'next page' icon shows the url as '.../?nggpage=2' and links to a totally wonky page displaying nothing.
Embedding gallery on another page however, shows the link to the next page as '.../currentPageName/?preview=true&preview_nonce=f8...blah blah' and behavious itself properly, i.e. reloads the gallery with it's next set of pictures.
Anyone got any idea how/why/what the hell is going on?
