Exposure is a jQuery image gallery plugin. Its 0.51 version was released yesterday.
Exposure offers a neat way of creating highly functional image galleries.
It weighs about 17kb, which is pretty standard for high-end plugins.
There are features, too: disable or enable thumbnails and controls; show or remove captions; keyboard navigation on and off; etc.
Perhaps the most remarkable features of Exposure are the numerous function calls, which allow you almost complete freedom of managing the plugin.
