Abstract
An avatar is an image people use for their online identity. Gravatar is a free service for providing globally unique avatars. Gravatar allows users to register an account using their email address. Users then upload an image to be associated with their Gravatar account. When the user uses the same email address on a website that uses Gravatar, the website retrieves the user’s avatar from Gravatar by using an image URL based on a hash of the email address. Websites, including Bullhorn, may freely use Gravatar to display the user’s image. Bullhorn displays the image next to posts and on the profile page.
