The power of Globally Recognized Avatar (aka Gravatar)

Gravatar has a very sleak concept but not many people know and understand it. It is one place for your display pictures and you can use the same at any Gravatar enabled website / application. Gravatar is currently used in WordPress, Movable Type, Drupal, Joomla and Mac OS X Addressbook.

Advantages are mainly on the user end where he/she can change one photo and reflect it in multiple places. It includes support for content-rating etc.

Here, I will show how it is implemented in PHP

$email = "";
$default = "";
$size = 100;

$grav_url = "".md5(strtolower($email)).

Now use it in your HTML as

<img src="<?php echo $grav_url; ?/>" width="< ?php echo $size; ?>" alt="Gravatar" />
