This is exactly what I've been looking for... A script/plugin that has perfectly fused Social sharing, deep linking of images (for SEO) & a lightweight/clean lightbox that works great on Mobile & desktop. But I purchased it because it does WAYYYY More that the 3 simple things I was looking for. One of the biggest surprises I had was the social sharing feature. It works perfectly! I had a client share a single image from a gallery to their Facebook. The format was clean & simple. But the results were amazing. When a Facebook user clicks to view the image, it takes them to my website where the gallery is & opens the lightbox to display the exact image that was shared. My website traffic spiked over the next 24 hours as my clients Facebook friends clicked to view the image. They spent an average of 2 minutes on my site & visited an average of 7 other pages before returning to Facebook. I'd term this method of social sharing a huge WIN! This is by far the most versatile & easy to use plugin. They also make great recommendations of other free & premium plugins to enhance the usability of WP Media Library. Bravo! You've done a fantastic job on this plugin. I'm sure this will become my go to script for galleries & portfolios to display images, videos, & custom posts.
My background: I've used dozens & dozens of gallery & lightbox scripts & plugins. I'm a programmer, so I've coded scripts into plugins & themes to get the functionality I wanted. But I've always been left looking for new scripts, because the next project needs something a little different.
