Enhanced Gravatar WordPress plugin: WP-SnapAvatar

Gravatar needs no introduction; many blogs and communities use it to display commenter avatars. There's no need to register in every place—avatars are generated through the email used in comments, with the address encrypted via MD5 so it cannot be obtained by third parties. OK, that’s not the focus of this article. For a detailed understanding, you can refer tocala’s article. Here, I want to introduce a plugin that enhances Gravatar's functionality. When a commenter’s email does not correspond to an avatar, if they have provided a URL, this plugin will take a screenshot of the URL and use it as the avatar. This is called WP-SnapAvatar.
