Avatar is a JavaScript library for showing Gravatars or generating user avatars.

There are several examples on the website.

var avatar = new Avatar(document.getElementById('avatar'), {
  'useGravatar': false,
  'initials': 'MC'
});

/* or */

$('#avatar').avatar({
  'useGravatar': false,
  'initials': 'MC'
});

This example will render an avatar with my initials "MC" as the image.

Avatar is highly customizable and most options are self explanatory:

useGravatar: true # Allow Gravatars or not.
fallbackImage: '' # URL or Data URI used when no initials are provided and not using Gravatars.

# Initial Avatars Specific
initials: ''  # Initials to be used.
initial_fg: '#888888' # Text Color
initial_bg: '#f4f6f7' # Background Color
initial_size: null    # Text Size in pixels
initial_weight: 100
initial_font_family: "'Lato', 'Lato-Regular', 'Helvetica Neue'"

# Gravatar Specific
hash: null  # Precalculated MD5 string of an email address
email: null # Email used for the Gravatar
size: 80    # Size in pixels
fallback: 'mm'               # Fallback Type
rating: 'x'                  # Gravatar Rating
forcedefault: false          # Force Gravatar Defaults
allowGravatarFallback: false # Use Gravatars fallback, not fallbackImage

<script src="md5.js"></script>
<script src="avatar.js"></script>

Avatar expects a window.md5() function to be defined in order to generate the hashes needed for Gravatar. One is provided as a sperate file if you would like to use your own or don't plan on using Gravatar.
