Hi @vboudon -
Welcome to the Local Community!
Are you by chance using a page builder like Elementor or Divi?
Sometimes there are issues with images and the way things display generally over Live Links with Elementor and other similar builders.
There are some suggestions in this thread I would recommend trying:
Let me know if that’s the case.
Otherwise, my next question would be regarding SSL - is the site running over https://
and the media files are http://
? That would be a mixed content issue and cause images to not display.
Let’s start there!
