In the New Web UI, an image associated with the current user is displayed at the top right corner of the application page when the IModelApplicationWeb.CurrentUserDisplayMode is set to CaptionAndImage or Image. To provide an individual image for each user, do the following:

  • Declare a property of the MediaDataObject type in your User business class.
  • Apply the CurrentUserDisplayImageAttribute attribute to the class and pass the property name to it.

    public virtual MediaDataObject Photo { get; set; }
    // ...
