Right!!! That it was, many thanks, I recommend including
that code in gnus, but maybe I am really the only one
interested.


Another thing which is related but concerns sending email.
While I can of course use (and in fact I do very often) the
TeX-to-char function for outgoing email which allows to send
converted symbols such-as and then can be read by other
email programs, the same is not true of
org-preview-latex-fragments, since it saves the png in a
subdirectory. 


I wrote a relative simple function which attaches all the
relevant png, but the result looks ugly. The reason is that
the mail is sent in principle as plain text, with embedded
png.

Now I learnt about 2 extensions for Thunderbird, which rely
on the same idea however their result looks much nicer since
they use htmlized email (which I normally dislike) so in
short will gnus at some point allow and support html email.
