The step below you can customize this plugin:

1. The forumla has Class tex. You can add custom CSS for tex in your CSS style file.
2. $regex = '#\$\$(.*?)\$\$#si'; in plugins/mimetex/mimetex.php define the format of a formula. If you want to use [tex][/tex] to wrap a formula, just change $regex to $regex = '#\[tex\](.*?)\[/tex\]#si';.
3. var $server = "http://l.wordpress.com/latex.php?latex="; is URL of the latex service. Sometimes, it doesn't work(however, it never happened to me), you need to change to a new one. Just search public mimetex at Google to find a new one. Or create your own one. As writed below, it is quite easy.

Install your own latex service

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.cgi or 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\beta to make sure it works.
• change var $server to appropriate one like var $server = "http://yourdomain/cgi-bin/mimetex.cgi?";
• You need to change the $img_format to corresponded image type your service generated. As in the case of MimeTex, the generated type is gif.
