JH Image Popup supports five different popup technologies: SqueezeBox (Joomla's popup), Colorbox, lightbox2, Magnific Popup and Swipebox. The code is loaded via CDN so you don't clutter your Joomla installation with unnecessary files. Just pick a popup technology in the plugin configuration, save, and your frontend is ready.
You find more documentation and the download link on the JH Image Popup page.
This page contains several images that are included via the regular Insert Image mechanism of Joomla's editor, no extra shortcodes are added. Since the plugin JH Image Popup is active, all <img>
tags are converted to be clickable and open in a lightbox popup window. Right now, lightbox2 is activated for this website.
