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
