This site has a title page and plan, and a concluding page. There are two sections in between.
The first is made up of a page of thumbnail photos. The second is a sequence of full sized photos with text commentary. These can be viewed as a slide show using the central arrow, or by manual navigation using the small outer arrows. Even better, the keyboard arrow keys can be used.
Clicking on a thumbnail takes us to the full sized photo. Closing the full sized photo by clicking the cross at top left returns us to the thumbnail page.
There are also several pages of ‘zoomed in’ photos. Use the keyboard back arrow key to return to the original photo.
