/*
Plugin Name: Slideshow Gallery
Plugin URI: http://wpgallery.tribulant.net
Author: Tribulant Software
Author URI: http://tribulant.com
Description: Feature content in a JavaScript powered slideshow gallery showcase on your WordPress website. The slideshow is flexible and all aspects can easily be configured. Embedding or hardcoding the slideshow gallery is a breeze. To embed into a post/page, simply insert <code>[slideshow]</code> into its content with an optional <code>post_id</code> parameter. To hardcode into any PHP file of your WordPress theme, simply use <code>&lt;?php if (function_exists('slideshow')) { slideshow($output = true, $post_id = false, $gallery_id = false, $params = array()); } ?&gt;</code>.
Version: 1.3.1.3
