This is the entirety of my header section. I'm sure there are redundancies etc. But again, the clean vanilla of Emacs 25.1.1 and org-mode 9.0.2 is defaulting to producing png's.

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, 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, but that's not MathJax. What am I doing (thinking) wrong?

I use
#+HTML_MATHJAX: align: left etc...
Works well.

Then you can control appearance through CSS. For instance:
.MathJax_Display {
    color: #080;
    margin: 0;
}

Have fun
