Sometimes I find myself in need of a GIF image of an equation or two. I want to be able to generate them quickly and easily, but I find that my MikTeX setup on Windows isn't helping.
Fortunately, Google found a utility that converts LaTeX to an image at EquationSheet.com. All I have to do is type in a snippet of LaTeX, hit the "convert" button, and I can see the equation rendered as an image. Even better, I can copy the URL and paste it into another HTML page as an image tag. Just what the doctor ordered!
