title: Take a screenshot from a website from commandline or with python
body: <p>i will take a screenshot from this page: <a href="http://books.google.de/books?id=gikDAAAAMBAJ&amp;pg=PA1&amp;img=1&amp;w=2500">http://books.google.de/books?id=gikDAAAAMBAJ&amp;pg=PA1&amp;img=1&amp;w=2500</a> or save the image that it outputs.</p>
  
  <p>But i can't find a way. With wget/curl i get an "unavailable error" and also with others tools like webkit2png/wkhtmltoimage/wkhtmltopng.</p>
  
  <p>Is there a clean way to do it with python or from commandline?</p>
  
  <p>Best regards!</p>
