jQuery responsive gallery and lightbox – (jrGal).
This script allows you to embed a slick responsive gallery into your website page or mobile app. Its easy to setup and works smoothly.
If you are creating a mobile-viewable (responsive) website. This gallery/lightbox will work fluidly with any screen size! It automatically adjusts to fit the view port size. Desktop OR mobile 
Personal note:
I tried to find a slick responsive gallery with a nice responsive lightbox, but could not find any. I needed a smooth one for my client and since I was unable to find one just the way I needed it to work, I built this one. Give it a try, you will see the difference. There’s no bloat, my code is tidy and compact. Thanks!
