blueimp Gallery is a touch-enabled, responsive and customizable image and video gallery, carousel and lightbox, optimized for both mobile and desktop web browsers.
It features swipe, mouse and keyboard navigation, transition effects, slideshow functionality, fullscreen support and on-demand content loading and can be extended to display additional content types.
This is the official WordPress plugin for the Gallery lightbox functionality.
By default it automatically adds lightbox functionality to image links ending with gif, jpg, jpeg and png extensions. The plugin provides an options page to disable the automatic feature and to restrict the list of media types. It is also possible to add lightbox functionality for a link manually.
