  • Gravatar (an abbreviation for globally recognized avatar) is a concept for globally-unique avatars which was invented by Tom Werner. On Gravatar, users can register an account based on their email address, and upload an avatar to be associated with the account. Gravatar plugins are available for popular blogging software; when the user posts a comment on such a blog that requires an e-mail address, the blogging software checks whether that e-mail address has an associated avatar at Gravatar. If so, the Gravatar is shown along with the comment. A Gravatar avatar can be up to 512 pixels wide, is always square and is displayed at 80 by 80 pixels by default. If the uploaded avatar is larger or smaller, the avatar is scaled appropriately. Each Gravatar is rated with an MPAA-style age recommendation, which allows webmasters to control the content of the Gravatars displayed on their website. To eliminate spam, e-mail addresses are hashed with the MD5 cryptographic hash function. This prevents spambots from harvesting e-mail addresses. (en)
