Avatar display settings

The final section on this page is labeled Avatars. Just as I mentioned in Chapter 2, Getting Started with WordPress, an avatar is an image that is a person's personal icon. Avatars in WordPress are provided through Gravatar, a service available at https://gravatar.com/ that lets you create your personal online profile, which is going to then to be consistently used on other websites across the web. By default, avatars will show up on your blog if you leave the Avatar Display box checked, which is visible near the bottom of the discussion settings page.

The second box, Maximum Rating, will tell WordPress when it should not show avatars that have been rated as too explicit. Remember the rating we set when uploading a new picture to Gravatar? This setting here is the place where you can choose which pictures you want to allow on your site (selecting the G rating is advisable).

The third box, Default Avatar, tells WordPress what avatar to use for visitors who do not come with their own image.
