I updated the image in my Gravatar but my old picture still shows up.
Is this a cache issue?
Do I need to log out and then log back in?

Jeff Atwood has stated that gravatar images are cached, so if it hasn't been very long, wait and it should change eventually. I do not believe logging in and out would influence this at all, since your gravatar is shown to everyone, not just you. Your logging in and out (of Stack Overflow) should have no affect.
Interesting note: your user page has not been updated, however the image for this question and on the questions page has been. I'm sure the user page will catch up, I just thought it was interesting.
You need to log out of Gravatar.
Gravatar doesn't seem to invalidate its cache until you are logged out. Either by doing so manually, or waiting for the session to expire (on their end).
I have actually prevented the cache from being invalidated, by continuing to visit
http://gravatar.com everyday. I didn't realize at the time it was preventing the site from invalidating the cache.
I've had problems where my browser (Safari) refused to update my Gravatar before, no matter how many times I refreshed. If you haven't, I suggest closing your browser, restarting it, and reloading your profile. If it still doesn't change, try flushing your cache, restarting, etc.
If that doesn't do it, I don't know what will, but it's definitely not StackOverflow's fault. I'd suggest filing a bug report with Gravatar.
I'm one of the Happiness Engineers working with Gravatar right now. Someone kindly pointed us in the direction of this thread, so I thought I would stop in and just point out a few things.
First, you can always check your Gravatar for any email address at:
Enter your email address into the form and you can see how your Grav will appear to a site that requests it, including ratings.
We are currently investigating a caching problem that occurs when a default Gravatar is specified in the querystring of the image request ("d="). We know this is happening and hope to have it fixed soon.
In the meantime, if you need a forced refresh of your Gravatar cache please file a support request and we can do that for you.
If you have any other questions feel free to leave me a message or contact us at Gravatar.
All you have to do is:
This works because Gravatars are not stored on the website you're using - they're stored on Gravatar so you need to refresh your cache there and you're done.
There are multiple sources for this problem:
One is using a different email address. (And note that though for Gmail addresses like
john.doe+whatever@gmail are all the same, they are different addresses with different avatars for Gravatar.)
Regular caching, in which Gravatar tells the browser to cache for 5 minutes. Just wait.
Caching at Gravatar. Wait a bit more.
(Some say one needs to log off too?)
You might have set some explicit rating, or no rating at all, while Stack Exchange requests PG.
Issues with the Gravatar CDN, which (like in July 2012) for some parts of the world might serve images that were actually changed weeks ago. Also, as Stack Exchange uses different formats (profile 128×128, user card 32×32, expanded user card 64×64), some sizes might then be okay, while others are not. Even problems like these might be solved by waiting a bit longer, or maybe uploading some new image might trigger a new synchronization. Regardless if that helps or not: I guess you'll need to contact their service desk, giving the details about the server you're using.
Some technical insight in CDN issues:
Peeking into the
Server header in the HTTP response (using something like Chrome's Developer Tools or Firebug in Firefox) will reveal which server you're using.
Like using the Frankfurt EdgeCast server, a two week old 64×64 image might be just fine:
Cache-Control: max-age=300 Content-Disposition: inline; filename="a80f263bea9df760a7d8932cd415ce3e.jpeg" Content-Type: image/jpeg Date: Fri, 13 Jul 2012 12:23:04 GMT Expires: Fri, 13 Jul 2012 12:28:04 GMT Last-Modified: Fri, 29 Jun 2012 08:10:29 GMT Server: ECS (fra/5950)
Last-Modified: Fri, 29 Jun 2012 08:10:29 GMT is the date the avatar was changed. (For some time, it would use the subscription date, but that was solved.) But for the very same image, the 128×128 version might show a default avatar:
Cache-Control: max-age=300 Content-Type: image/png Date: Fri, 13 Jul 2012 12:20:34 GMT Expires: Fri, 13 Jul 2012 12:25:34 GMT Last-Modified: Wed, 11 Jan 1984 08:00:00 GMT Server: ECS (fra/5950)
Last-Modified: Wed, 11 Jan 1984 08:00:00 GMT indicates it's a default, generated avatar. But for that very same image, the Amsterdam EdgeCast server might give the expected image:
curl --compressed --head \ http://www.gravatar.com/avatar/a80f263bea9df760a7d8932cd415ce3e?s=128&d=identicon&r=PG Cache-Control: max-age=300 Content-Disposition: inline; filename="a80f263bea9df760a7d8932cd415ce3e.jpeg" Content-Type: image/jpeg Date: Fri, 13 Jul 2012 12:34:32 GMT Expires: Fri, 13 Jul 2012 12:39:32 GMT Last-Modified: Fri, 29 Jun 2012 08:10:29 GMT Server: ECS (ams/49DF)
Also, for the very same image but without the rating
r=PG, the Frankfurt server might serve the expected image too:
Cache-Control: max-age=300 Content-Disposition: inline; filename="a80f263bea9df760a7d8932cd415ce3e.jpeg" Content-Type: image/jpeg Date: Fri, 13 Jul 2012 12:40:29 GMT Expires: Fri, 13 Jul 2012 12:45:29 GMT Last-Modified: Fri, 29 Jun 2012 08:10:29 GMT Server: ECS (fra/5950)
Like said: report CDN problems to Gravatar.
You need to follow up with gravatar.com , not us.
That said, usually you just need to wait a few days.
The problem for me was that Safari was caching my profile image. It had already updated on Gravatar's site, but even when I reloaded my user profile my image didn't change. I ended up emptying the cache and restarting my browser, and that solved it.
