Yes, codecogs do provide that. But I hate those images and MathJax ones do render much much better. So, what I do is simply change the codecogs image generation part and put a $-$ around them and thus using codecogs just for typing Latex equation.
>But there are a few other issues to handle like rendering maths on answer/comment submit without page load
This is actually important- a user wont like his typed stuffs to appear in $-$. And this is not hard to do though this requires a core hack. So, what I do is keep a separate file for this. Since, anyway I'm doing this I thought of sharing the entire code so that anyone requiring Latex can get them in Q2A without the trouble I had to do at beginning.
