BuddyPress: Don't Load Gravatar for Member Avatars
Stops BuddyPress from requesting Gravatar images for members without an uploaded photo and uses the local mystery-person image instead, for privacy and speed.
Snippet Library
Users snippets for WordPress
Snippets for user accounts, roles and profiles: extra profile fields, new columns in the users list, last-login tracking and tighter control of what each role can do. Handy for membership sites, client sites and teams with many authors.
Initials Avatars Instead of Gravatar
Replaces Gravatar images with colored circles showing each person's initials, generated locally, so no visitor data is sent to Gravatar.
Profile Picture From the Media Library
Lets users pick a profile picture from the Media Library on their profile screen; it replaces their Gravatar everywhere.
Your Own Image as the Default Avatar
Adds your own image to the Default Avatar choices under Settings > Discussion, used for people without a Gravatar.
