– The Mathematical text rendering system [MathTran](http://www.mathtran.org/) which uses JavaScript to contact a web service that converts TeX embeded in the *src* attribute of an tag into PNG graphics file. E.g. becomes ![tex: int_0^1 x^2 dx](http://www.mathtran.org/cgi-bin/mathtran?D=1;tex=%5Cint%20_0%5E1%20x%5E2%5C%2C%20dx).
