I have a customer with an old site and hundreds of images in Nextgen galleries. Needed desperately to modernize, and I was considering using my own plugin for photoswipe with masonry grid (not public), but that would have meant re-uploading hundreds of images and reconstructing galleries... JIG's ability to override Nextgen means we don't have to move anything, my client can keep using the Nextgen interface she is accustomed to, and we get a gorgeous and modern display. All in a few clicks and $29. So worth it. I cannot thank you enough!
