mimeTeX: LaTeX Math for Wordpress

This Wordpress plugin allows you to embed \LaTeX math formulas into your posts without having LaTeX installed at your server. Just like this:

\normalsize f(x)=\int\limits_{-\infty}^x~e^{-t^2}dt

It was originally developed by Anlak.

The plugin just downloads the image from the public cgi script in Forkosh and copies it to your wp-content/cache.

I modified the plugin to correct two problems: the cgi script url has changed and there were some problems with tags and characters encoding. For the first issue I placed a script in my page that will keep the url updated without changes in the plugin code.

You can download this new version here.

Installation procedure:

  1. Copy both file to your “/wp-content/plugins”-folder.
  2. Create the folder “/wp-content/cache” and chmod it to 777.
  3. Go to the administration interface. In Plugins, activate it.

Enjoy!
