Gravatar checker

Gravatar checker is a tool used to verify whether a specific email address is associated with a Gravatar account. Gravatar is a service that allows users to upload a profile picture and associate it with their email address. When a website that uses Gravatar displays a comment or profile information for a user with a Gravatar-associated email, the user's profile picture is automatically pulled from the Gravatar service. A Gravatar checker can be used to determine if an email address has an associated Gravatar account and profile picture.
