Your profile picture is powered by a third-party platform called a Gravatar. Click on your name in the upper right-hand corner of Oasis and then select Edit My Profile. Once you’ve done this, scroll down to your profile picture. There is an option to connect to the Gravatar website where you can create an account. Make sure that your email in Oasis is the same you enter in your Gravatar account. It usually takes a day or two for your Gravatar to update and your profile picture to show up in Oasis.
