In wordpress, a better way to check if an author has a gravatar or not. Sometimes you might want to check to see if a gravatar exists and not display any image if there isn't one. Uses the wordpress HTTP and caching apis. A better version of this: http://codex.wordpress.org/Using_Gravatars#Checking_for_the_Existence_of_a_Gravatar
