  • 'retro' (a 8-bit arcade-style pixelated face)
  • 'robohash' (a robot)
  • 'monsterid' (a monster)
  • 'wavatar' (a cartoon face)
  • 'identicon' (the "quilt", a geometric pattern)

  • 'gravatar_default' (the Gravatar logo) Default is the value of the 'avatar_default' option, with a fallback of 'mystery'.
• force_default bool
  Whether to always show the default image, never the Gravatar.
  Default false.
• rating string
  What rating to display avatars up to. Accepts:
  

  • 'G' (suitable for all audiences)
  • 'PG' (possibly offensive, usually for audiences 13 and above)

  URL scheme to use. See set_url_scheme() for accepted values.
  For Gravatars this setting is ignored and HTTPS is used to avoid unnecessary redirects. The setting is retained for systems using the 'pre_get_avatar_data' filter to customize avatars.
  
• processed_args array
  When the function returns, the value will be the processed/sanitized $args plus a "found_avatar" guess. Pass as a reference.
• extra_attr string
