The ProPhoto block was designed to give a smoother user experience while viewing a set of images, displaying a large primary image with a horizontal filmstrip of thumbs, providing a quick way to jump to other images without having to scroll down the page. It's has smooth transitions between images and 'degrades gracefully', so people can still use it with javascript turned off.
Here are some of the features it provides:
