This plugin renders LaTeX formulas into images.

Of course you will need LaTeX installed for this to work. The plugin
also uses mhchem.sty, which in Debian is in the texlive-science package and
may not be part of a regular texlive installation.

## examples

	\[[!teximg code="\ce{[Cu(NH3)3]^{2+}}"]]
	\[[!teximg code="\frac{1}{2}"]]
	\[[!teximg code="E = - \frac{Z^2 \cdot  \mu \cdot e^4}{32\pi^2 \epsilon_0^2 \hbar^2 n^2}" ]]

To scale the image, use height=x:

	\[[!teximg code="\ce{[Cu(NH3)3]^{2+}}" height="17"]]
	\[[!teximg code="\ce{[Cu(NH3)3]^{2+}}" height="8"]]

If no height is choosen the default height 12 is used. Valid heights are: 8, 9,
10, 11, 12, 14, 17, 20. If another height is entered, the closest available
height is used.

To add an alt text to the image, use alt="text":

	\[[!teximg code="\frac{1}{2}" alt="1/2"]]
