Hello Fanny-
Thanks for reaching out, I’m sorry to hear about the difficulty with your images showing up in Chrome.
I’m making the assumption that the images you’re talking about are the ones with the links, “Infos sur les cours,” “Prix,” and “Horaires.” Please let me know if I’m wrong about that assumption.
The reason that these images aren’t showing is because they’re actually the images from your DreamHost Staging site, http://www.example.com.dream.website. Notice in that address, the protocol is http, but your main website is https://example.com, with https.
Chrome won’t display “insecure” content loaded over http on a website that is using https. What you’ll need to do in this case is edit those images to use the URL of your production website, not your staging website.
One way you can accomplish this is to use a plugin like Better Search and Replace. Search for “www.example.com.dream.website” and replace those with “example.com” (making sure to swap out “example” for your domain name).
