http://chart.apis.google.com/chart?cht=tx&chf=bg,s,FFFFFF00&chco=AACCFF&chl=i\hbar\frac{\partial}{\partial t} \Psi(\mathbf{r},\,t) = \hat H \Psi(\mathbf{r},t)

Put your code in the chl parameter. The chf parameter lets you specify a background color in RGBA, chco lets you set the foreground color in RGB. When you drop it in inside of an image tag you get this:
