Make examples grow when clicking on them

On https://www.khanacademy.org/math/multivariable-calculus/thinking-about-multivariable-function/ways-to-represent-multivariable-functions/a/vector-fields there's at least 2 small example images that when clicking on them nothing happen; luckily my browser has an option that right-clicking on them can make them appear in a new tab and switching to the new tab the example then take the whole width (of the window).

I'd like it if when clicking on examples they would grow.

Thank you for your consideration
