What's the best way to incorporate LaTeX into a WordPress blog?
It should render in every major browser (IE, FF, Safari, and Chrome).
There are a few available plugins of varying quality. One problem most of the plugins have is the vertical alignment of the LaTeX-generated characters. Equations sit too high on the line most of the time. The only plugin I've found to get around this problem is WP-QuickLaTeX which works seamlessly. However, it doesn't handle displayed equations, only inline equations. I don't know of a plug-in that gets vertical alignment correct and handles displayed equations. (And I've tried them all as far as I know.)
It's not WordPress specific, but jsLatex has been an option I've seen people use to get LaTeX into browsers.
