This gallery is better for large images, as if the image is larger than the screen resolution it is scrolled when you click on it. You can change some settings in the Root.as file, such as thumb size etc. The gallery uses the TweenLite class, which you can download from here: http://blog.greensock.com/tweenliteas3 but it is also included in the source. The classes are AS3, and the fla is in CS3 so you need Flash CS3 to open it. All the images shown here are from http://www.sxc.hu , if anyone wants a list of authors then I'll post it. Anyway, enjoy :D
