Gravatar Avatar Image

The term "Gravatar Avatar Image" refers to a universal avatar image service associated with an email address, primarily used on platforms like WordPress, JetPack, and various forums.

What is it?

• Gravatar stands for "Globally Recognized Avatar."
• It is a service provided by Automattic (the company behind WordPress) that allows users to use the same profile picture across multiple websites.
• The system works by hashing a user's email address. If a user has uploaded an image to the Gravatar service associated with that email, the website displaying the user's profile will automatically fetch and display that image.

How it Works:

1. Registration: A user signs up on gravatar.com and uploads an image.
2. Email Association: The user links their email address to that image on the Gravatar site.
3. Auto-Display: When that same email address comments on or registers for a site that supports Gravatar, the site calculates the hash of the email (e.g., MD5 hash), checks the Gravatar server, and displays the corresponding image in the "Avatar" position.

Technical Details:

• Image URL Pattern: The URL typically follows this format: https://www.gravatar.com/avatar/[HASH]?s=[SIZE]&d=[IDENTITY]&r=[RATING]
  • [HASH]: The MD5 hash of the lowercase, trimmed email address.
  • s: Size in pixels (e.g., 80, 200).
  • d: Default image if no Gravatar exists (e.g., mp for mystery man, identicon, retro).
  • r: Rating (g, pg, r, x).
• Privacy: It does not store personal data other than the email and image, and the email hash is not reversible.

Common Usage:

• WordPress Blogs: Default avatar for commenters.
• Developer Communities: (e.g., GitHub, Stack Overflow, PHP.net) use Gravatar to identify users.
• Forums: Many legacy and modern forums integrate Gravatar for user identification.

How to Change or Manage:

1. Go to gravatar.com.
2. Log in with the email address used on the target site.
3. Upload a new image.
4. Adjust visibility settings (e.g., "Only show on sites I specify" or "Show on all sites").
