I want to put some icons in a web and I want to know how can I detect if a person has a gravatar so in case they don't have one I want to show another icon, can anyone help me?? Thanks in advance Belén
I tried a while ago to implement this and finished doing a column in the users table saying wants_gravatar:boolean. If it was true, then the user.face method would return their gravatar picture like so:
if wants_gravatar? "http://www.gravatar.com/avatar.php? gravatar_id=#{Digest::MD5.hexdigest(email_address)}" else self.avatar ? self.avatar.public_filename : DEFAULTFACE end
but actually checking wether the email address mapped any pictures in gravatar or not, i could not find a way. I decided that if the user wanted a gravatar an didnt have one, hed just get the gravatar logo. it was so much less painfull to implement.
It still appreciate if anyone knew how to perform the check.

but none of them seems to implement any check, if a gravatar exists as far as I can see, the only thing possible is to set one of three default images:
