Mediawiki Javascript Slideshow
Installation: Add this to LocalSettings.php require_once('$IP/extensions/JavascriptSlideshow/JavascriptSlideshow.php');
From version 1.1 HTML5 output needs to be enabled in mediawiki. It is enabled by default, so you shouldn't need to do anything, as long as $wgHtml5 isn't set to false in your LocalSettings.php.
