Tons of features. Default "recommended" values are not set automatically when first installed, which is a little odd. Once you set those, and start experimenting, the power of this plugin shines. I've tried other lightbox plugins that have some features this lacks (like displaying image EXIF data, or providing original file download). But the other features of this lightbox far overpower this. This includes ability to work on a per page basis, detect any image links and convert to lightbox links, display slideshows, and fully customize styles of lightbox, transition effects and more.
