Implement Gravatar support to allow users to use their Gravatar images as profile avatars on the platform. This feature will enable users to have a consistent and recognizable profile image across various platforms that use Gravatar. Upon registration or profile editing, users can opt to link their Gravatar account, automatically importing their Gravatar image as their profile picture. This integration simplifies the process of maintaining a uniform online presence and enhances user identification and personalization on the platform.
