Hello
I am starting to use org-preview-latex-fragment also in non
org buffers, including message buffers.
What would be extremely helpful is to actually send the
images generates in the message buffers as images.
Preview-latex provides such a functionality
preview-copy-region-as-mml, from a LaTeX buffer.
Of course the 2 preview functions org-preview and the
latex-preview function work differently. I had a look
preview-copy-region-as-mml and it is not clear to me how to
make if work for png generated by org-preview-latex-fragment
in a message buffer.
Maybe some of the maintainers of org mode or auctex are
interested in having a look?

I ran into that the other day.
I think it would be very useful to have preview-buffer work
on non-latex buffers.
http://www.gnu.org/software/auctex/manual/preview-latex.html#ToDo has
the following paragraph which suggests this might not be trivial:
The current ‘gs.el’ interface is fundamentally flawed, not only because
of a broken implementation. A general batchable and daemonizable
rendering infrastructure that can work on all kinds of preview images
for embedding into buffers is warranted. The current implementation has
a rather adhoc flavor and is not easily extended. It will not work
outside of AUCTeX, either.
An additional convenience would be integration within gnus. Typical use
cases are:
- I receive a plain text mail from someone discussing maths, with inline
$\frac a b$. Ideally, I would just press a binding that would render the
maths with preview-buffer.
- I want to send math in an email. I would write inline $\frac a b$, and
gnus would create a multipart message with the $$s in the plain text
part, and images in the HTML part.

Concerning org-preview-latex-fragment: I have some code
which indeed attaches the png generated by this
function. However it is very primitive.
org-preview-latex-fragment generates pngs in a subdirectory
called ltxpng. These pngs are then inserted in
the buffer where org-preview-latex-fragment was executed. Since
one cannot be sure that the ltxpng directory is non-empty, IMHO it
should be deleted before generating the png.
This is done by function
my-delete-ltxpngdir, which needs the trashcan pkg.
Then a very simple modification of an already existing
function does the rest:
message-attach-all-png-from-ltxpngfolder.
I attach it if you want to test it.
