Photos navigation: To see all of the photos in sequence, just click on the large format photo here on the left (each time you click you will move forward by one photo).

This is the quickest and most effective way of viewing photos. Indeed, while you are looking at the photo on screen, the system downloads the next photo in the background, which shortens waiting times.

If you only want to see some of the photos, move your mouse on the above "index" button and choose the miniature and click on it to show it in large format.

To return to the main menu, click on the above "up" button.
