Hi Ivo,
On page
https://xavierm19.sg-host.com/index.php/la-compagnie/livre-dor the images on slide 1 and 3 can't be opened into lightbox. All the other slide images can be opened.
I looked for image names, jpg or png ... this kind of logic, without success.
I enclose site access details.
Many thanks in advance for your help.
Regards.
