or aynchronous browser loading (use the .standalone version in the /dist folder)

import Load from 'storm-load';

Load('/content/js/async/storm-modal-gallery.standalone.js')
    .then(() => {
        StormModalGalllery.init('.js-modal-gallery');
    });

To create from pure JS and triggered from any event:

import ModalGallery from 'storm-modal-gallery';

let gallery = ModalGallery.init([
    {
        src: 'http://placehold.it/500x500',
        srcset:'http://placehold.it/800x800 800w, http://placehold.it/500x500 320w',
        title: 'Image 1',
        description: 'Description 1'
    },
    {
        src: 'http://placehold.it/300x800',
        srcset:'http://placehold.it/500x800 800w, http://placehold.it/300x500 320w',
        title: 'Image 2',
        description: 'Description 2'
    }]);

//e.g. Open the gallery by clicking on a button with the className 'js-modal-gallery__trigger'
document.querySelector('.js-modal-gallery__trigger').addEventListener('click', gallery.open.bind(gallery, 0));

Options

{
    fullscreen: false,
    preload: false,
    totals: true //show current and totalnumber of images
    scrollable: false, //add className to apply CSS to support scrollable content
    single: false // separate single images, do not collect into a gallery
}

e.g.

ModalGallery.init('.js-modal-gallery', {
    fullscreen: true
});

This module depends upon Object.assign available in all evergreen browsers. ie9+ is supported with polyfills, ie8+ will work with even more polyfills for Array functions and eventListeners.
