This plugin implements <a href="https://photoswipe.com/" rel="nofollow ugc">PhotoSwipe</a> to display an image gallery in a lightbox. To include images in the image gallery, you need to link them to “Media File”. The lightbox opens when you click on an image.

Tailored Media

WordPress plugin to enqueue <a href="https://fancyapps.com/fancybox/3/" rel="nofollow ugc">fancyBox3</a> lightbox script.
Should work automatically, any links to .jpg, .jpeg, .gif, .png will become lightbox links.
Current version: 3.5.7

Tailored Lightbox

I can even have the lightbox effect with the native Gutenberg galleries.

Thanks.

Works Perfectly !

Enqueue the Fancybox lightbox script, and automatically load for links to image files.
