Websnap script

Looking for a free or ( not to much ) paid script that can go to sites and make pictures to the index page. After doing so showing it on my site … or placing it on the server ( so I can use it from there ).

Any ideas?

Our screenshot processor does that. It visits the URL, gets a thumb of the site you specify, even big ones, and then connects to FTP and uploads to the server.

Not exactly what I need. Still looking.
