NETTUTS presents a very nice tutorial on "Creating A MooTools Photo Gallery".

All the steps of creating this MooTools gallery is very well described and the source code is ready to download for instant use.

MooTools Photo Gallery

The gallery has a functional interface which enables you to browse between thumbnails and the original-size images easily.

P.S. It is not dynamic & all the thumbnails are loaded when the gallery loads. For this reason it may be suitable for galleries with <30-40 images.
