I am trying to find a PHP script (or a script in a different language) that after passing a URL, it takes a screenshot of the website for that URL. So for example if I pass stackoverflow.com, it should take a screen shot of the website (in this case the homepage), keep it on the server, and provide a link to that pic.
Is there an easy way to do that?
I know it is possible because that's how they take thumbnails for websites in Alexa for example.
If you need more explanation of what I mean please just post a comment and I will explain more.
Thank you :)
