+# Gravatar Plugin
+by [Klaus Weidenbach](http://friendica.dszdw.net/profile/klaus)
+
+This addon allows you to look up an avatar image for new users and contacts at [Gravatar](http://www.gravatar.com). This will be used if there have not been found any other avatar images yet for example through OpenID.
+
+Gravatar is a popular, but centralized and proprietary service where people can store an avatar image for their email-addresses. It is widely used on many pages, for example to display an avatar for comment functions, profile pages, etc.
+
+* * *
+
+# Configuration
+## Default Avatar Image
+If no avatar was found for an email Gravatar can create some pseudo-random generated avatars based on an email hash. You can choose between these presets:
+
+* __Gravatar__: default static Gravatar logo
+* __MM__: (mystery-man) a static image
+* __Identicon__: a generated geometric pattern based on email hash
+* __Monsterid__: a generated 'monster' with different colors, faces, etc. based on email hash
+* __Wavatar__: faces with different features and backgrounds based on email hash
+* __Retro__: 8-bit arcade-styled pixelated faces based on email hash
+
+See examples at [Gravatar][1].
+## Avatar Rating
+Gravatar lets users self-rate their images to be used at appropriate audiences. Choose which are appropriate for your friendica site:
+
+* __g__: suitable for display on all wesites with any audience type
+* __pg__: may contain rude gestures, provocatively dressed individuals, the lesser swear words, or mild violence
+* __r__: may contain such things as harsh profanity, intense violence, nudity, or hard drug use
+* __x__: may contain hardcore sexual imagery or extremely disurbing violence
+
+See more information at [Gravatar][1].
+
+## Alternative Configuration
+Open the .htconfig.php file and add "gravatar" to the list of activated addons:
+
+        $a->config['system']['addon'] = "..., gravatar";
+
+You can add two configuration variables for the addon:
+
+        $a->config['gravatar']['default_avatar'] = "identicon";
+        $a->config['gravatar']['rating'] = "g";
