PHP class for creating and displaying PNG userpics based on users' input data, such as email or any other personalized information.

Class generates images like Gravatar service does.

Not compatible with PHP version < 5

Uses GD and PHP >= 5.3.0

If you want to make it work on PHP less than 5.3.0, find string

array_walk($shape, function(&$coord, $index, $mult) { $coord *= $mult; }, self::SPRITE_SIZE);

and rewrite it for using create_function() instead of lambda-function.

Usage:

$av = new Avatarco;
$av->init('email or other data', 100);
$savedImage = $av->SavePicture('./'); //to save image on disk and return its path

or

$av->ShowPicture(); // to display image

Working demo can be found at http://uf8.ru/avatarco.php (reload for random image)
