Many Lightbox clones exist, including the excellent Slimbox by Christophe Beyls, which was also written for MooTools and was the inspiration for QuickBox. So what's different about it?
First, it was written from the ground up for version 1.2 of the lightweight MooTools framework. MooTools, especially version 1.2, is in my opinion the best framework available, and allows code to be lightweight and stable.
Second, QuickBox was written for speed, allowing you to zip through images as quickly as possible. One improvement made to facilitate this is allowing use of the mouse wheel to scroll through images.
Also changed are a more stable background, captions that can be localized for other languages, and a few other minor improvements.
Update: If you own a hosting company and would like to contribute, I am always interested in server space, especially VPS setups. Please send me a message if you would like to help out, and thanks!
