I want to write formulas in Mathematica format in my blog, inside tag's formula. What js should I use (and what libary), to replace those tag's, with http://www.wolframalpha.com/ search result image, when Dom gets loaded? For example: Limit[((3 + h)^(-1) + -1/3)/h, h -> 0] gets replaced with: ![alt text][1] If it's to complex or can not be done with javascript, please explain why.
