Using LaTeX within WordPress

Renderu – LaTeX parsing WordPress plugin
Adapting from Titus Barik’s “LaTeX Equations and Graphics in PHP” titled article from the Linux Journal magazine, I was able to write a plugin for WordPress that enables me to include LaTeX-type
 $\sum\limits_{j = 1}^m {p\left( X \right)H\left( {Y|X = x_i } \right)} $
in the form of a PNG file format as :
(Although there is problem with multi lined entries such as matrix)
Barik’s article explained the method for Linux, but it can easily be run on a Windows environment (as it is been running on my computer at this very moment). Just install a LaTeX distribution like MikTeX and an image manipulation package like ImageMagick and it’s ready!

Solved the multi-lined entry problem by switching from standard plain TeX to AMS-LaTeX.
plain TeX code for a 3×3 matrix :
$$
\matrix{
1 & 2 & 3 \cr
4 & 5 & 6 \cr
7 & 8 & 9 \cr
}
$$
and the same matrix in AMS-LaTeX format:
\[
\begin{array}{*{20}c}
1 & 2 & 3 \\
4 & 5 & 6 \\
7 & 8 & 9 \\
\end{array}
\]
