Plugins for the Coppermine Photo Gallery are add-ons that use the plugin interface of Coppermine. Read up the documentation that comes with Coppermine to find out more, e.g. how to install a plugin. Coppermine version: cpg1.4.x Plugin name: Light Box Plugin version: 1.2 Plugin author: Sander Weyens, pluginized by jeepguy_1980 Plugin announcement thread: http://forum.coppermine-gallery.net/index.php/topic,59013.0.html This plugin will override the default popup that embeds the fullsize picture and it will show a nice Lightbox popup instead. It features a slideshow as well, you can navigate through the images in the selected album with the arrow keys or with your mouse. Converted Sawey's mod, LightBox JS for Full Size Popup Slideshow, into a plugin. This is my first attempt to do any work in PHP, so I cannot really support this plugin. As I learn more about PHP, I expect to enhance this plugin with a configuration panel.
