ver 3.4.10 revert the change in ver 3.4.8.

ver 3.0: Using MathJax and Images to display LaTeX formula.
Using MathJax and images, this plugin provides a general and elegant solution to add and display your mathematical fourmula, no matter the visitors are visiting your blog or read from Google Reader.
You can type the formula in LaTeX, in title, posts, pages and comments:
$$\alpha+\beta\geq\gamma$$add an inline formula
$$!\alpha+\beta\geq\gamma$$add an LaTeX equation in math mode(it will be displayed centerly in a single line).
\(\alpha+\beta\geq\gamma!\)display the source of the LaTeX formula. Just add a
The plugin uses copy of Mathjax from their CDN Service by default, you can also install your own MathJax. It’s easy, just following the link in the setting page of this plugin.
There are lots of websites provide such services, for example, wordpress.com and Google Charts. The plugin provide four candidates for you, and you can choose any of them or customize it to use your own LaTeX image generating service.
Other features are added in version 3.2+:
- The mathjax script is loaded only needed. This would spead up your blog a lot.

As I known, MimeTex is the easiest one to build up:
- download appropriate mimetex executable program from
http://www.forkosh.com/mimetex.html. change the file name to
mimetex.exe(the postfix depend on your system). Upload it to your
/cgi-bin/diretory, make it executable by your webserver(chmod 777 will do the trick).
- check url
http://yourdomain/cgi-bin/mimtex.cgi?\alpha\geq\betato make sure it works.
var $serverto appropriate one like
var $server = "http://yourdomain/cgi-bin/mimetex.cgi?";
- You need to change the
$img_formatto corresponded image type your service generated. As in the case of MimeTex, the generated type is
- The background of my blog is black and the words are black. The equation by this plugin is black and the backgound is white. How can I make them consistent?
When the generated images are transparent, they are fit to any background. Otherwise, you need to use a LaTeX image service which supports custom background and foreground color.
http://l.wordpress.com/LaTeX.php?bg=ffffff&fg=000000&LaTeX=is a good candidate. The bg parameter defines background color and fg parameter defines foreground color, you can customize them to any RGB colors.
