If you have added a profile picture to the IdP (identity provider) account you use to log in, it is now displayed on the sidebar instead of your initials.
For example, if you log in with your enterprise account, Scrivito uses the image from your enterprise system. With Google, Scrivito will display the image Google provides.
Technically speaking, the OpenID Connect picture claim serves as the profile image source. If no profile picture is available, your initials are used as a fallback.
