A gravatar, or globally recognized avatar, is quite simply an image that follows you from site to site appearing beside your name when you do things. Avatars help identify your posts on blogs and web forums. The function to add Gravatars to your theme is called: get_avatar.

First you need to enable your wordpress theme to display avatars. Afer logging into Wordpress admin, go to Settings > Discussion and for the Avatars.

The function returns a complete image HTML tag of the Avatar.

The function is called as follows:

<?php
echo get_avatar( $id_or_email, $size = '96', $default = '<path_to_url>' );
?>

Once you enable the to display avatars, set the php code in your comments.php in the appropriate area where you want the avatars to appear. The PHP code will be like this:

<?php if(function_exists('get_avatar')) { echo get_avatar($comment, '40'); } ?>

The default output is when using the above function is listed below. Various classes are applied to img element to help you with element styling:

<img alt='' src='http://gravatarurl_or_default'
class='avatar avatar-$size' height='$size' width='$size' />

If the gravatar reverts to the default image due to a lack of an e-mail address (i.e. a pingback or trackback), whether you have specified a default or not, the img element will also be given a CSS class of avatar-default.

Setting up gravatars on your site is easy, you don't even need an account! Plugins are available for leading blog software and content management systems, and our tutorials will have you running gravatars in no time. To request a gravatar from our servers, you simply add an image to your users activity with an "src" attribute that points to our gravatar image generator and includes an MD5 hash of the user's email address. Since all gravatars are rated with an MPAA style rating, you can restrict your site to show only gravatars whose content you are comfortable with.

A Gravatar is a dynamic image resource that is requested from a server. The request URL is presented here, broken into its segments. The URL always begins with:

http://www.gravatar.com/avatar.php?

A mandatory parameter named gravatar_id follows this. Its value is the hexadecimal MD5 hash of the requested users' email address with all whitespace trimmed. The value is case insensitive.

gravatar_id=279aa12c3326f87c460aa4f31d18a065

The parameters are:

• id_or_email (required): Author’s User ID (an integer or string), an E-mail Address (a string) or the comment object from the comment loop. Note: with most comment templates you can use $comment here, in order to display the gravatar of the commenter. In other templates, you can use get_the_author_id() here.
• size (optional): Avatar display size (max is 512).
• default (optional): Absolute location of the default avatar to use
