When you search Google for any keyword or website, it shows you results in link form. But recently, I came across an excellent extension, SearchPreview, which enhances search results by adding thumbnail preview of the website along with the link.
Install the extension and go to Google homepage.
Search for any result you want to and you will see the thumbnails of websites in you search results.
And you are done. I personally like this extension a lot and would recommend you to use it. If you like this, check out how to Manage Yahoo services in Chrome and how you can easily edit images in Google Chrome.
