Gravatar (globally recognized avatar) is a popular third-party profile image service. You can choose to use a Gravatar image with your Talentd profile.
If you don't already have a Gravatar account, you will need to create one at Gravatar.
If you do have a Gravatar account, the Gravatar image is associated with a specific email address. If your Gravatar account uses the same email address that you use for your Talentd account, the Gravatar image should already be a part of your profile.
