I can only hope that this Gaussian will appear:

\mathbb{P}(X \le x) = \int_{-\infty}^{x} \frac{1}{\sqrt{2 \pi}} \exp(- y^2/2) dy

How to do it:

1. Install the WP-Cache plugin. Note that you have to muck with file permissions and it’s somewhat non-intuitive.
2. Install the MimeTeX plugin.
3. Stress out about the fact that for some equations the terminating quote ” in the alt tag for the image has turned into a fancy quote. Come up with a hack involving placing an empty img tag right after every piece of LaTeX. Hope that you figure out a way around it.
