Setting up your avatar is actually made easy with WordPress. WordPress utilizes a system called Gravatar, which stands for globally recognized avatar.
The first step to getting your avatar set up, is by hovering over your account name on the very top right hand side of the screen, and clicking on "edit profile."
If you scroll down on this new page, there is a contact section. Within that section it has an e-mail address field. It should look like this..
Take note of what e-mail address you have in that field, because the same e-mail address will have to be used on Gravatar.
The next step, is to go to Gravatar's website by following this link.. www.gravatar.com
On the top right hand side of the screen, click on the "sign in" button, and proceed by creating a new account with the same e-mail address that you took note of before.
Once your account is created, click on "My Gravatars" at the top of the screen. You'll see your e-mail address listed there, and you then can click on "Add a new image" underneath section 2.
Follow the on-screen prompts to upload a picture, crop it, and to select a rating. Once you've completed these steps, you'll be able to refresh your page on WordPress. If you look at your account name in the top right-hand side of the screen, you'll notice that it automatically populated your new avatar!
