Why do we need it?

In some case the images in wordpress posts are small and hard to see for users. Also, the default Gallery Block of WordPress Gutenberg does not work as a slideshow. To solve this problem, we can use lightbox.

How to do it?

Install Simple Lightbox plugin

Link the image to the full size image

Simple as that.
