Gravatar
May 30th, 2008 . by editor
A globally recognized avatar or to put it short, a Gravatar, was conceptualized by Tom Werner. It is simply an avatar image that appears beside your name everytime you comment on gravatar enabled sites.
Usually, the size of a Gravatar is 80 by 80 pixels. There is also a rating for each image, allowing the webmasters to control the content of to Gravatar to be displayed on their website. Email addresses are hashed with the MD5 cryptographic hash function to eliminate spam and prevent spambots from harvesting e-mail addresses.
