Hey Eric,
Thanks for you tip, but I guess the dvipng command works well. Things get
kind of strange, since if I type $2^6$, Org recognizes it, and generates the
right results, which means, it could find all the latex package needed. But
if I try
--------
#+BEGIN_LaTeX
\begin{equation} % arbitrary environments,
x=\sqrt{b} % even tables, figures
\end{equation} % etc
#+END_LaTeX
--------
It will end up with some strange picture in ltxpng directory, which is just
all black, nothing...
Do you have any idea?
Thanks a lot!
Chao
