Today faced the trouble in activating author box for one of my client in his website. Out there some one might face the same problem in future. So here is the solution and explanation of what caused this error.
By default WordPress supplies few options as how you can add image to the author / Users. See the picture below.

admin panel >> Settings >> Discussion
You have to mark the show avatar checkbox.Then select the gravatar from the radio box.
Now go to /wp-admin/users.php and select the individual users.
Click the edit profile link. Inside the user profile page, genesis gave the option to enable author box below the post and in the author archive page.
Its not end here. To make the author profile to be appeared in the website, that particular author should be registered with [fancy_link color=”#ff0d13″ link=”http://en.gravatar.com/”]Gravatar[/fancy_link]
This is how it works, the email id provided in the user profile is taken and it will be used as an identifier to get the author image from the gravatar.
If the author is not registered with gravatar, then default gravatar image will be used.
