wkhtmltopdf renders web pages to PDF using WebKit and works great on Windows, for what it's worth. It's just one more step to go from PDF to PNG. The results were great when I used it, but I'm not sure how it deals with e.g. Flash.

wkhtmltopdf is excellent software. I use it to generate previews of text/html parts in emails at http://spamalyser.com/

either use aviary.com or:

all you need is imagemagick

wkhtmltopdf www.google.com google.pdf && convert google.pdf google.png

results aren't nearly as good as the browser addon but it works
