SFQuickTeX is small application that makes converting LaTeX expressions to images easy. Select the environment you want your expression to be evaluated in, enter code, click "Create image" and save the image in nearly any format you like.
Additionally it offers the possibility to convert all LaTeX expression between <latex>...</latex> in a html file to png files, that are then inserted as <img /> tags into the html source.
