Supersized is a jQuery plugin that automatically resizes (background) images to the size of the browser while maintaining image dimension ratio and runs them as a slideshow. There is no extra whitespace, no scrollbars – the entire browser window is always filled. It is lightweight and plays nice with Firefox, Safari, Opera, IE7, and IE6.
