Here's a very simple ORG file:
--------
#+OPTIONS: LaTeX:dvipng
* Test file
\begin{equation}
x=\sqrt{b}
\end{equation}
----------
When I export this to HTML (Org-mode version 7.8.11 (release_7.8.11-12-gc55405 @ c:/emacs/site-lisp/org-mode/lisp/)), the equation comes out blank.
The HTML file contains the following code:
<img src="ltxpng/test_660c6efb146974e9d77e2de45f258385867ef389.png" alt="\begin{equation}
x=\sqrt{b}
\end{equation}"/>
However, directory ltxpng is empty.
I'm running Emacs 24.0.97 under Windows Vista with MikTeX 2.09 installed and PATH set so that I can call pdflatex, dvipng, etc. from the command line just fine.
Any thoughts about what might be going wrong?

Investigating further, the log file associated with the tex file listed above shows the following:

Pass the -shell-escape flag to LaTeX. Refer to the minted.sty documentation for

So now I can see what the problem is, but how do I tell org-mode to call latex with the -shell-escape flag?

You can customize org-latex-to-pdf-process (or
org-e-latex-pdf-process[fn:1] if you are using the new exporter). In my
case, I have
,----
| org-latex-to-pdf-process is a variable defined in `org-latex.el'.
| Its value is ("texi2dvi --pdf %f")
| Original value was
| ("pdflatex -interaction nonstopmode -output-directory %o %f" "pdflatex -interaction nonstopmode -output-directory %o %f" "pdflatex -interaction nonstopmode -output-directory %o %f")
`----
but texi2dvi probably does not exist on windows (and you still have to
patch it even on linux). Just add --shell-escape after every pdflatex
(or whatever command is invoked on windows).

Footnotes:
[fn:1] NB: different spelling in the two cases - not only the added "e-" but
also the missing "-to".

In my init.el, I have
(setq org-latex-to-pdf-process
'("pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"
"pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"
"pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"
"pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"))
The problem is that when I export to HTML with the dvipng option, it's calling latex, not pdflatex, so I don't think this option has an effect.

Ah, right: that's hardwired and needs source code changes. The call is
in org.el:org-create-formula-image-with-dvipng. This was reported by
Ista Zahn (see http://thread.gmane.org/gmane.emacs.orgmode/50533). I
would encourage you to submit a patch for this[fn:1] - maybe make it
conditional on the value of org-export-latex-listings.
