Thanks. I'll put it on the list.

As for PhantomJS, I hadn't heard of it. I was originally rendering the screenshots with Selenium and the FirefoxDriver. They came out looking good, but performance was abysmal and when a page froze up I needed a mechanism to kill firefox manually.

Now I'm using Wordpress's Mshots service, but I'm looking at a couple of python tools to generate headless screenshots.
