[Resuelto] My header main image is not displaying in translated version

Background of the issue:
I am trying to display my picture (logo) in the French version of the header on my website. The issue can be seen on this page: enlace oculto.

Symptoms:
The header main image is not displaying in the translated version. Instead of my pictures, I got a broken picture logo. The pictures do not direct to the same place on the server: EN: enlace oculto, FR: enlace oculto.

Questions:
Why is the header main image not displaying in the translated version?
How can I ensure the images direct to the same place on the server for both language versions?
