Plone's doc does it, so why don't we give it shot?

Seems we can use Robot Framework inside Sphinx to automate things.

Python 3 support for Selenium is up in the air so we'd need to port the Robot/Selenium integration package to Python 3 first, and then go from there.

Alternatively, we can use something like this: http://phantomjs.org/screen-capture.html

Wiring it into Sphinx would be super-awesome.
