When I communicate the following URL to my contacts: https://alter-ego.dev/homepage by messaging, by email, on the networks, etc., the photo associated with it by default is the photo found here :

https://alter-ego.dev/homepage/#Lauteur

Would it be possible to change this?
Ideally, I would like to associate this URL with a very specific image.
Is it possible ? How ?

Thanking you.

Thanks !
