    The following variables offer control over how things are displayed.
 
 ‘gnus-gravatar-size’
      The size in pixels of gravatars.  Gravatars are always square, so

      List of image properties applied to Gravatar images.
 
 ‘gnus-gravatar-too-ugly’
      Regexp that matches mail addresses or names of people of which
      avatars should not be displayed, or ‘nil’.  It default to the value
      of ‘gnus-article-x-face-too-ugly’ (SeeX-Face).
