Which system allows anonymous portraits of images?
Does anyone know what a system is that allows blogs / websites to generate a random image for anonymous commentators? Its always the same picture, if you enter the same name and email, it seems very helpful but can't keep track of what it is.
It has been used here on stackoverflow and I've seen it on several other sites and blogs.
Thanks!
Identicon is what I was actually looking for, but Gravatar's answer allowed me to find it! Thanks Jeff! I assume lazy registration is handled separately.

You are looking for identifiers .
Alternatives to this are wavatar and monsters .
Both Gravatar and Libravatar (open source alternative and federated version for gravatar), maintain it as a fallback when the custom image is not available for the email address.

Use gravatar, this is what you use to change your account image. You can register for free here: gravitar
If you want to change your profile picture, go to user settings, click "Change", then change your picture. Register, then select an image. Make sure the email address you signed up for matches the one on your account. Enjoy.
