GleeTeX is a Python module to create images from formulas. It can parse HTML documents and replace all occurrences of some formula through images. Each image will get an alt attribute as well, which is useful for screen readers or text-mode browsers. It can also just create formula images out of LaTeX formulas and the process can be embedded into a web application.

GleeTeX is able to convert multiple images concurrently and it also keeps a cache of already converted formulas, speeding up the conversion.
