Thanks Alex that explains the problem, I’m working on window 10 on a Microsoft edge.
Thanks for you all your help.
When you click on a photo it enlarges the photo and opens in what I think is called the splash gallery, you then swipe the image to move on to the next one which is fine. II wanted to add a thumbnail bar to that, If that makes any sense. A link below might explain what I’m trying to achieve better.
The image at the bottom of the page “added thumbnail navigation to the lightbox”
