The vServer platform includes the ability to create, manage and display photogalleries. We use the Gallery package from Menalto Software.
This can work as a standalone package or can be used for image management, with the galleries created then being integrated with Movable Type, using the MTPhotoGallery Plugin by Brandon Fuller. This works simply by placing the name of the gallery folder in the keyword field, with [] around it, thusly: [Kenya05].
