sigplus Image Gallery Plus
Description
sigplus Image Gallery Plus or (sigplus in short) is a straightforward way to add image galleries to an article with a simple syntax. The galleries exhibit the well-known lightbox effect: when a thumbnail is clicked, the corresponding image appears in a pop-up window overlay, without navigating away from the current page.
The plug-in implements features that are usually found only in image gallery Joomla plug-ins that are either commercial or require paid club membership. sigplus ships with all features included, there is no upgrade to a commercial professional version.
