Add "https://www.alpestour.com/phototheque/alpestour/V%C3%A9lo%20de%20route/" to the "Settings / Admin / Upload path" box. Facebook needs the full URL, but the skin doesn't know it if you don't provide it.
Good morning and thanks for your help.
It does not work. Many changes and settings to make for a photo next to a share. So I prefer to share the link and manually add a photo, it's just as fast and simple. I like things simple. thanks again
Originally it was a single check box, but thanks to FB's monopolistic moves and the EU regulations it became harder and harder to make it work with each year. Perhaps one day I will remove this facebook thing altogether, as it's really hard to follow how they change the requirements every few months.
