This question already has an answer here:

I have an auto-generated gravatar as my display on SO. I wish to associate that unique, but non-descriptive, gravatar in other places (such as github). I have grown rather fond of it. Is there anyway to do this? Do I have to go to gravatar and actually sign up for an account?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

It's a Gravatar. This is not SO specific. Any website which uses Gravatars will show the exact same one, provided you use the same email address. – Bart Jun 20 '13 at 14:32
@Bart that's an answer ;) You should post it as one – doppelgreener Jun 20 '13 at 14:37
@JonathanHobbs Yeah, but I'm pretty sure this is a dupe. That's what I'm looking for atm. – Bart Jun 20 '13 at 14:38
Speaking of gravatars, it's always a little weird for me when I see your posts, because ours basically differ only in saturation. – Josh Caswell Jun 20 '13 at 19:28

Your gravatars are generated based on hashed values of your email addresses. It has been explained in details on Gravatar's Creating Hash page.

  1. Trim leading and trailing whitespace from an email address
  2. Force all characters to lower-case
  3. md5 hash the final string

As long as you keep using the same email address, you'll have the same image generated. In your case, the image is:


and the hashed value will be: e328e5547ae249f222721cba4a7010eb

Well, it turns out the email associated with the gravatar is different than what I though it was. Many moons ago when my SO account was created I think I had some sort of account confusion. So now I just have to get github to take that gravatar email and pop that image in. Maybe it will show up after a little bit of a wait? – demongolem Jun 20 '13 at 16:56
@demongolem There are 7 types of default images Gravatar provides. Stack Overflow uses identicon among them. – hjpotter92 Jun 20 '13 at 17:01
