title: Phantomjs - take screenshot of a web page
body: <p>I have a URL (for e.g. <code>http://www.example.com/OtterBox-77-24444-Commuter-Series-Optimus/dp/B00A21KPEI/ref=pd_sim_cps_4</code>) and want to take a screenshot of it and preview it on my web page. Meaning, the user clicks on the preview button and PhantomJS needs to preview the web page as PNG/JPEG</p>
  
  <p>I'm ok with using any other open source too.</p>
