A lightbox opens your images/videos when you click a thumbnail. It’s a technique to isolate the photo/video in a larger view, without navigating away from the page. Most major sites use some form of lightbox. The area around and behind the photo/video is usually darkened. Several extra features can make the lightbox experience better, such as social sharing capabilities. This page helps you gain insight of the differences between lightbox solutions and help you decide which lightbox to use for your gallery.
