This plugin uses the jquery implementation of fancybox and makes use of [attr] style selectors by adding a section to the wordpress header.

FancyBox

Loved it as a developer as it has nothing but a plain fancybox.



straight pulldown of fancbox

Enables fancybox on all image links including BMP, GIF, JPG, JPEG, and PNG links.

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.
