[FIXED] How to generate unique images from hashed informations with PHP GD?

Issue

Good day,

in the website I'm working on, I would like to display an unique image to the user generated with a hash from his email address.

Should I generate fractals ?

If so, how can I make em "unique" or more specifically, easier to recognize by the user who has just logged on ?

I pretty much like the associated user's images by Stackoverflow to their new users.

I am using PHP GD.

Thank in advance for any tips to achieve this.

Solution

Here's some source code that you can run: http://www.exorithm.com/algorithm/view/unique_image
