Gravatar is giving me errors https

Hello,

Gravatar is giving me errors on my https SSL site. It is the only thing that is not compatible on my site and is breaking my SSL.

Here is the code snippet if I view source that breaks it:
`”default_up”:”http:\/\/www.gravatar.com\/avatar\/00000000000000000000000000000000?d=mm&size=24″,”default_cr”

How do I get Gravatar to come in secure so it doesn’t break my ssl?

Any help greatly appreciated ??
