Gallery 3 with Total CMS gallery integration is excellent.
However, is it possible for the lightbox to open up within the page width and current position (modal) and not full-screen to the top of the page?
The reason I ask is that the Gallery 3 lightbox action breaks certain aspects of the Foundation layout - particularly Equalised stacks but others as well the page refreshes after the forced full-screen.
Try this on any MB or iMac. (This rather complex beta site is not optimised for mobile yet!)
