Photo Galleria is a simple, yet elegant, plugin for photographers, designers and Wordpress 2.5 users alike who want to beautify their Wordpress photo galleries using the jquery framework. The Photo Galleria plugin synchronizes Galleria with Wordpress’ built-in media manager. Simply upload photos as normal and the Photo Galleria plugin will create a photo gallery with fade-in and fade-out effects common on flash-based websites. All the transitions happen inline without having to navigate to multiple Wordpress attachment pages. Pretty neat, eh?

Photo Galleria displays the thumbnail images that Wordpress creates for you and displays the original, high resolution uploaded image. Both are constrained proportionally via css. You can control their display size via the two CSS files included with the plugin. By default, the thumbnails display at 125px by 125px square and the image displays at 950px wide. Virtually every aspect of the presentation of Photo Galleria can be controlled via CSS.

Before you start

1. This plugin uses the jquery javascript library. Occasionally, jquery and other javascript libraries don’t play nice together. If your plugin doesn’t work, make sure you don’t have a plugin that installs conflicting javascript libraries into the head of your site.
2. Possibly the best solution to help ensure your javascript libraries stay updated and don’t conflict with other libraries is to install Google AJAX Libraries API Plugin. Then, delete the javascripts from this plugin and from the head of your site. Finally, add something along the lines of the following to your themes functions.php file:
   if(function_exists(’wp_enqueue_script’)) {
wp_enqueue_script(’jquery’);
}

   This will then load the jQuery library for your theme in a manner that will make changeable to the google libraries by the plugin. - from Barry, plugin author.

3. This plugin uses the jquery javascript library. If you already have jquery installed, you might want to remove this code from the plugin:
   <script type='text/javascript' src='".get_bloginfo("url")."/wp-content/plugins/
photo-galleria/js/jquery-1.2.6.min.js'></script>

Plugin Development To Do List

1. Enable “active” class on linked thumbnail images. This will enable a default main image to load, instead of thumbnails.
2. Debug Mac Firefox DOM issue. On Firefox (Mac), the thumbails load briefly behind the main image.
3. Make main image use the medium size image, not the original
