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.
