You may have noticed that your image already appeared on your profile, this is because you’ve already created a gravatar account or in some cases, it connected through your email.
The easiest way, though, is to use gravatar. To do this – go to http://en.gravatar.com/
Click on Sign in and fill out the form. You’ll want to use the same email that you’re using with wordpress (which is how you log into the columbines site)
After filling in the email address, you’ll be sent an email to confirm the acknowledgement. Open that email and click the link to confirm.
Now you’ll be asked for access to the wordpress account. Make sure to approve.
Now follow the pages to add images and upload the image you want to use, check your sizing though as your image can’t be more than 1 MB. Once you’ve got it loaded, you can check out the snippet, crop it down and confirm the layout. It will ask you about the “rating” of the image. Most likely, G rated should be the standard.
Now you should be able to log in to the columbines site (log out if you were logged in during this process) and upon the fresh log in you should see your image.
