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?

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.
