Excellent Plugin for LaTeX

This plugin is very easy to use and supports many more LaTeX packages and features than most plugins since it interfaces with a web service that provides a full LaTeX implementation. The author responds to issues very promptly. So far, I’ve never encountered any significant issues and everything has worked very well. The images look great; they default to SVG, so they are scalable and high-quality. I have three primary requirements: to render inline mathematics (obviously), commutative diagrams, and arbitrary drawings; this plugin supports TikZ and xy-pic (and a host of packages that are common among LaTeX distributions) which fulfills all of my requirements. It provides local caching of images; you can also use it with WP Super Cache and a CDN (content delivery network) for improved performance.
