Default Image of author is not loading

Problem:
If author has not uploaded his profile pic then the default image i.e `img/anonymous.png` is shown to user. But on the front page/Home page, image is not loading.

Solution: Image is render from the Javascript through location.hostname + path_to_image which is missing 'http://' at the start so image is not loading.
Add 'http://' to the start will fix the issue.
