Pretty Photo Lightbox Navigation?Browser Info Environment
I'll take a look at this and get back to you within 24 hours.
Just to inform you that this will be included in the next release of Gallerific. So stay tuned to the update. The release will probably be early next week.
Thanks so much for your work.
(sorry for the late response)
Thanks for your patience. I've already updated the add-on and it should now support a gallery for the lightbox.
Hope that helps.
