1. type url of the website - https://www.google.com


2. based on point 1. it should capture whatever is appearing on the home page of www.google.com (i.e. search bar etc)


3. and this captured homepage screenshot should show on our site.

we tried using the following and getting some error. Tech Stack Language used for the website - PHP Yii Application used - phantomjs, console version of webkit Server hosted - Amazon AWS Linux
