mathtex is a cgi program that lets you easily embed LaTeX math in your own html pages, blogs, wikis, etc. It parses a LaTeX math expression and immediately emits the corresponding gif (or png) image, rather than the usual TeX dvi. The following is just an example of use copied from the homepage: CGIDIR defaults to /var/www/cgi-bin, but pass a differnet value if your local installation needs something else.
