At first, I thought this plug-in was fantastic. The lightbox for my gallery page looked better than before, and the Pinterest button worked fine. But then I noticed that pictures on my site that were not linked to the NextGEN Gallery plug-in were doing very strange things when someone clicked on them. Instead of a normal enlargement, they were blown up to an enormous size that was not scrollable. Visitors could not see normal enlargements of anything. I deactivated this plug-in, and it fixed the weird enlargement problem. But when I went back to my original Lightbox installation, it won't work, no matter what I do. I'm probably going to wind up having to reinstall NextGEN Gallery and set the whole thing up all over again, including a gallery page that took me a long time to put together, just to get it back to what it was before I unfortunately installed this plug-in. What a waste of time.
