Minimal design + responsive layout + fullscreen gallery = Fullscreen theme. It is a gorgeous photo gallery WordPress responsive theme where the photos are put in center focus. Users can toggle to fullscreen mode by clicking on the fullscreen button and pressing escape key to exit the fullscreen mode. The fullscreen gallery can be individually assigned to Posts and Pages. For the regular WordPress gallery, there are two display options: photoswipe or lightbox. You may use Fullscreen to showcase lightbox media such as popup image, video, and iframe window.
