Does not do anything
Just does not work. This topic was modified 6 months, 3 weeks ago by Benjamin Stocker.
Worked straight out of the box!
Couldn’t be simpler. Downloaded, installed, activated and now all my post images open in a lightbox. Brilliant!
Simple Yet Awesome
I like the simplicity of the plugin and it works with WP native image block. The ability to automatically group single images on a page or post and browse through them in the model box is great.
