Hi Carsten,
The option "#+OPTIONS ^:nil" did the trick with underlines and hats,
but Greek
letter are still replaced. Since they are ignored by jsMath I get
the correct
equations and the only minor annoyance is that the font of the Greek
letters is
not as nice as if it were replace by jsMath (jsMath fonts are
equivalent to
latex fonts). If it is something easy to do, an option to also turn-
off the
replacements of Greek letters by org-mode would be nice, but don't
bother if it
is to much work.
You can just use LaTeX conventions and write $\alpha$ instead of the
lazy \alpha. That should do the trick.

I'll write the instructions of how to use jsMath with org-mode here
soon.
Thanks Carsten,

Hello org-users,
I know that it is possible to export equations as images if you set
the variable
org-export-with-LaTeX-fragments to t, but I prefer to use jsMath
(http://www.math.union.edu/~dpvc/jsMath/) for equation in HTML. The
problem is
that when org-export-with-LaTeX-fragments is set to nil org-mode
interprets
underlines, hats and Greek letters and replace them in the generated
HTML.
Would
#+OPTIONS ^:nil
already do what you want?
If you get this working, can I ask you to write up some instructions
on how to use this with Org and post them here?
Thanks.

I agree that this is nice in most cases, but I need them to be left
untouched,
since they will be later interpreted by jsMath when I'm viewing the
page in a
browser that supports java-script. Therefore, my "feature request"
is disabling
this smart behavior of org-mode when latex fragments are not
converted to
images.
I also need to add a line in the HTML header to load the jsMath
script, but this is
easily accomplished with the line
#+STYLE: <SCRIPT SRC="../jsMath/easy/load.js"></SCRIPT>
in the org-file header.
Here are some advantages and disadvantages about using jsMath
instead of images.
Advantages:
- It's really pretty when you have all the fonts installed and you
can zoom
without any loss of quality.
- No need to generate images when exporting
+ When you see the generated HTML page the jsMath script is run
each time you
reload the page. Because modern browsers are increasing more and
more the
efficiency of the java-script engine this is not a problem even
if there are
a lot of equations in the generated page.
+ On the other hand, creating images when exporting can take
considerable
time when there are man equations.
Disadvantages
- More difficult to setup
+ you have to install jsMath for authors, since you are creating
pages with it.
+ you have to install jsMath for users, that is, install the fonts
that will
be used. If this is not done, jsMath will use images for the
equations. You
won't need to generate images when exporting, since jsMath
already has all
images (it just put the pieces together)
- It is more inconvenient to send the generated HTML page to a
friend, since
your friend will need to install the fonts used by jsMath.
