Dynamic thumbnail creation of a webpage

How to get Flash to take a snapshot photograph of a webpage and display it as a thumbnail? The idea is similar to that found at http://www.hoppa.com (Firefox/Mozilla required).

I guess this would involve:
1- load a webpage in the background (hidden)
2- take a printScreen snapshot of that page
3- rescale and compress image
4- display the image in movie

I haven’t come across any useful examples on the net…
Do you know if Flash can do at least steps 1+2 ?:h: Or any other creative solution…

As an alternative, can I load a webpage in a Flash movieclip, with the site (text and imgs) scaled down to 10% ?

I hope this doesn’t involve:
-using any other language than Flash, except JavaScript
