Render math with MathJax
like the Chrome extension "Wikipedia with MathJax". It replaces the images with the LaTeX and lets the MathJax script render it. Way better typography with correct baselines and scaling so that it prints well too.

I would suggest using KaTex instead of MathJax.
It has better performances and is lighter.
You can find it here.

In case of "old fashioned" users, use of MathJax should be optional, like in the original wiki.
