For questions about how Gravatars are fetched and displayed on the Stack Exchange network. This is not for general Gravatar support inquiries.
Gravatar (an abbreviation for globally recognized avatar) is a service for providing globally-unique avatars based on your email address or IP address (when your email is unavailable). Users can upload an image to use on all sites which support Gravatars simply by using the same email address linked to their Gravatar account, or allow an image to be automatically generated.
This is not Gravatar support. If you have problems with your Gravatar account, including problems uploading images, adding email addresses, or anything else you do on the Gravatar site, this is not the place to ask your question. Use this tag for questions about how Gravatars are fetched and displayed here on the Stack Exchange network.
