email == ""

If the email is equal to an empty string or is not a valid email address, we get no avatar back. Is that the expected behavior? Should we use the default image if the email address is invalid???

We are relying on Gravatar to return a default avatar image if the email address is not valid or the string is empty. If you check the gravatar api, we specify a default image if none is found. However, if you wanted to use one of your own instead. You could easily make a change to inject an image url if nothing comes back.
