There is an additional menu item under the title image for Restaurant photos.
The image on the Home page (https://asoelie2e.fr/) is a rotating panorama (using Adobe Flash Player). On the other pages it is a static photograph. The file size is similar to the ordinary image so should not take any longer to download but the rotation will use more of your computer processor. Hopefully this will not cause any problems?
Under the image at the top of all the pages there is a grey scale with eleven gradations from black to white and ten more back to black. If your screen is adjusted correctly you should be able to see all the shades of grey.
