Dear Tim, John and Colin, You are right Tim, for Gnus, the solution to my problem was here :
https://www.emacswiki.org/emacs/MimeTypesWithGnus and here: https://lists.gnu.org/archive/html/info-gnus-english/2016-04/msg00002.html But I just realize that Gnus gives the choice to open "internally", or "externally"... :S Best wishes and many thanks for your very kind help, Jo.
