Customizing your event · For hosts
Likes and comments on photos
Both are on by default. Turn either off, and hide any comment you do not want shown.
Guests can like photos and comment on them without an account. To turn either off, go to Design → Look and feel → Gallery → Likes and comments and untick Guests can like photos or Guests can comment on photos. Some events are better without them — a memorial, for instance.
Comments are not screened automatically. While comments are on, the Photos tab has a Comments card listing everything guests have written. Tap Hide to remove a comment from the gallery; Show puts it back. Comments are hidden rather than deleted, so a hide can always be undone.
Turning comments off also hides the ones already there.
