Reply To: Bugs since the new update

The page is : chaleur-naturelle.fr

The sections that I am modifying : https://www.loom.com/share/dfa49e133c6f4c078944a307707e972b

2 issues
1/ The image is sometimes correctly displayed (file: correctly_displayed). Sometimes it is not (file: poorly_displayed)

2/ And second question: How do I display another photo for the mobile version?
