This site has a title page and a concluding page. There are two connected sections in between.
The first is 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 either the small outer arrows or the keyboard arrows.
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. Clicking on a zoomed in photo returns us to the thumbnail page.
