Slimbox2 Slideshow is a WordPress plugin used to display Lightbox effects on images. It supports image resizing to fit images in the browser window and automatic slideshow. With advantages over other existing Lightbox plugins being;

1. Slideshow can show entire WordPress images from multiple posts.
2. Automatically resizes images to fit in browser window.
3. Support for WordPress galleries with captions and Image Maps.
4. No need to modify exisiting image html, and can directly substitute existing plugins that use rel="lightbox".
5. Uses jQuery library, which means faster initial load.
