Drag & drop interface
Build your gallery using WordPress Drag & Drop interface. It’s well known, works great so why don’t use it. There is no need to reinvent the wheel. You don’t want to learn new UI over and over again.
Open your Gallery items using Lightbox view. In popup window you can use slider mode for better user experience and custom captions to display more information about each of them.
Upload some images, decide what kind of navigation and open method you want. We’ll do the rest. Your gallery will scale to look beautiful on any device.
