Setup

class "img-lightbox-link" can be any name you choose.

data-src is deprecated, but supported for compatibility.

href is required, and contains URL of your image.

For those who don't use 3rd-party scripts that interfere with links behaviour and don't force window.location they have no need in either data-touch="true" or {touch: true}.

When you have scripts that interfere, then to keep lightbox working, use {touch: true} or data-touch="true".

data-src or href doesn't matter, but you shouldn't enable touch override if you have a full screen image in a lighbox link and have no other space to scroll down.

<a href="https://farm1.staticflickr.com/955/27854475488_4f2b7f52e4_k.jpg"
class="img-lightbox-link"
data-src="https://farm1.staticflickr.com/955/27854475488_4f2b7f52e4_k.jpg"
aria-hidden="true"
rel="lightbox"><img src="https://farm1.staticflickr.com/955/27854475488_5f82a379ca_z.jpg" alt="Image Lightbox" /></a>

Initialize

imgLightbox("img-lightbox-link");

Tips

SPA / PWA developers don't need to bother: built-in class is added to a link.

That way you avoid multiple assignments to a single element.

Examples of event handling

(function(root) {
   "use strict";
   if (root.imgLightbox) {
   	imgLightbox("img-lightbox-link", {
   		onCreated: function() {
   			/* show your preloader */
   		},
   		onLoaded: function() {
   			/* hide your preloader */
   		},
   		onError: function() {
   			/* hide your preloader */
   		},
   		onClosed: function() {
   			/* hide your preloader */
   		},
   		rate: 500 /* default: 500 */,
   		touch: false /* default: false - use with care for responsive images in links on vertical mobile screens */
   	});
   }
})("undefined" !== typeof window ? window : this);
