== Gravatar Plugin

This plugin provides a handful of view helpers for displaying gravatars 

(globally-recognized avatars). 

Gravatars allow users to configure an avatar to go with their email address at

a central location: http://gravatar.com. Gravatar-aware websites (such

as yours) can then look up and display each user's preferred avatar, without

having to handle avatar management. The user gets the benefit of not having to

set up an avatar for each site that they post on.

== Installation

  cd ~/myapp

  ruby script/plugin install svn://rubyforge.org//var/svn/gravatarplugin/plugins/gravatar

or, if you're using piston[http://piston.rubyforge.org] (worth it!):

  cd ~/myapp/vendor/plugins

  piston import svn://rubyforge.org//var/svn/gravatarplugin/plugins/gravatar

== Example

If you represent your users with a model that has an +email+ method (typical

for most rails authentication setups), then you can simply use this method

in your views:

  <%= gravatar_for @user %>

This will be replaced with the full HTML +img+ tag necessary for displaying 

that user's gravatar.

Other helpers are documented under GravatarHelper::PublicMethods.

== Acknowledgments

The following people have also written gravatar-related Ruby libraries:

* Seth Rasmussen created the gravatar gem[http://gravatar.rubyforge.org]

* Matt McCray has also created a gravatar 

  plugin[http://mattmccray.com/svn/rails/plugins/gravatar_helper]
