A Piwik plugin that adds a profile photo from Gravatar based on the email address stored in the User Id field.
This plugin is compatible with Piwik 2 (see requirements below for more details).
What information do I need to make this plugin work? Make sure you are capturing the email address for your visitors in the User Id field.
Why do some of my visitors just display the Gravatar logo instead of a photo? Either there is no email address associated with the visitor or they do not have a Gravatar set up at gravatar.com
