Dear John,

Thanks for  your reply. In  fact my problem is  only at the  moment with
pdf links  in gnus, not  in usual org files.  (Maybe I should  switch for
mu4e, but I  hesitate and I would be  happy to find a tutorial  to do it
with gmail.)

I    have    solved    temporarily    the   problem    with    eimp    :
https://emacs.stackexchange.com/questions/2433/shrink-zoom-scale-images-in-=
image-mode

and the pdf in emacs are now more easily readable for me.=20

Best wishes, and again, to Colin and to you, many thanks.=20
