It's impossible. Gravatar doesn't actually operate on email addresses but MD5 hashes of them. There's no way to relate email addresses that have the same portion after the @ sign. If you send Gravatar an email that's not specifically in its database, it has no way to even tell what domain you are asking about. This is by design to ensure we all know ...


You can request anyone's avatar with curl like this: curl "http://gravatar.com/avatar/$(md5 -q -s nobody@example.com)?s=300" > avatar.png Replacing nobody@example.com with your (or anyone else's) email address, and 300 with the pixel size (up to 2048). For example, s=300 will get you a 300x300 pixel image. If you don't have access to a Unix command ...


Five years later, but you can now (and for quite some time) add additional email addresses to your Gravatar account. Just log in to your account, add the email address, click the link in the confirm email and you are done. Still not as easy an practical as a "+" wildcard, but quite doable.


Maybe you have to wait for some minutes, hours or days too for it to be updated on GitHub. But till then give this a try, go to your profile settings page https://github.com/settings/profile and change the Gravatar email at bottom (any random email) and reload the page, then put your valid email address in the input field and save, then refresh the page ...


You can use your current Gravatar image by selecting the web URL, but this will then be uploaded to Flickr's server, and will therefore not stay up to date with your Gravatar image. Basically this is no different to if you were to upload the image from your computer. Therefore you cannot use Gravatar as your buddy icon.


You can't prevent WordPress from using Gravatar, but you can head over to the Gravatar site & change which email ID can use which gravatar.


Well, before, you would have had to sign up with a Gravatar account. There's really no difference. They've simply unified their user credentials. So, yes, you need to create a WordPress.com account. Don't worry, that doesn't mean that you'll have a WordPress blog. You can just use it for your Gravatar.


This fix is easy. I will confirm this works since I work at the same organization as Brian Knoblauch. Simply navigate to ${github.url}/stafftools and navigate down to the 'enable gravatars' option (under settings tab) and enable it. The server will restart and your gravatars will now appear.


Gravatar doc specify 'd' parameter for that: Code exemple in PHP from Gravatar doc: $grav_url = "http://www.gravatar.com/avatar/" . md5( strtolower( trim( $email ) ) ) . "?d=" . urlencode( $default ) . "&s=" . $size;
