I've got an org file with Latex math markup, e.g. $x_2/y^3$. When I export
this to HTML, it produces png files for each markup and puts them in a
subfolder ltximg. Is there any way to skip this translating to pictures and
just use MathJax directly. I've seen this
<http://orgmode.org/manual/Math-formatting-in-HTML-export.html>, but my
setup seems to be defaulted to png picture production, not direct MathJax
rendering via "
http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML. I
understand that what's happening is this
<http://orgmode.org/worg/org-tutorials/org-latex-preview.html>, but that's
not MathJax. What am I doing (thinking) wrong?
