bildo is the esperanto for image
npm install -g bildo. You may need root.
For example, let's say we want a quick galery from a directory named pepper.
Run bildo pepper and access localhost:5000. You'll get something like this, with every image that's on that directory:
bildo <folder> --items [number] - How many items you want per page (default: 20)
bildo <folder> --port [port] -Which port to use (default: 5000)
bildo <folder> --nogrid - Don't display images on a grid
