A Gallery Page is designed to give an overview of a number of Pictures contained within the Gallery. These are shown as a grid of thumbnails which the user can then click on and see a larger version and more information. One can browse from picture to picture with a graphical preview of the next and previous images.
There were 6 pictures found.
