Gravatar change?

My avatar has changed: it was red and now it is green. Why is that ? (I'm just curious and definitely not complaining: I prefer the new avatar with its pleasantly soothing green.)

  • $\begingroup$ Did you change the email address in your profile? This thread may provide further information and maybe even an explanation. $\endgroup$

    $\begingroup$ I voted to close this question, as it seems to be an exact duplicate of the thread I linked to above. $\endgroup$

  • $\begingroup$ Ah, yes, I changed my email address, and that changed my colour. By the way, in the unlikely case that I wanted to upload my own avatar, is there a link explaining how to do that? I would have asked this as a meta question but I have become wary now and feel that it might again be an "exact duplicate" . $\endgroup$ Jun 25, 2011 at 9:58

    $\begingroup$ The avatars are handled by gravatar.com. I never used that site, but it looks self-explanatory. In the unlikely case that you mention you need to make sure that the email address you use here is the same as the one registered by gravatar. Indeed, your follow-up would probably closed as a duplicate because of this thread that may be more helpful than the last one I pointed out to you. $\endgroup$

  • $\begingroup$ To be a bit more explicit: The email address you enter in your user profile (click here for direct access) must match the one you registered at gravatar.com. Each time your avatar is displayed, math.SE sends a query to gravatar.com containing a hash (encoded version) of your address. Gravatar then sends back the picture you uploaded there, which is then displayed here. This is maybe not 100% accurate technically, but it explains that you need not fear about revealing your email address: it's never sent in plain text. $\endgroup$

    $\begingroup$ Thanks a lot, Theo. (We seem to meet a lot on this site and as far as I am concerned, I'm delighted. Judging from your reputation, the feeling is widespread...) $\endgroup$ Jun 25, 2011 at 11:06
