Notes

  • Must be used in a section ($addSection) inside a container ($addContainer).
  • Do not confuse this with $thumbnail[] which defines the thumbnail of a classic embed.
  • The URL must point to a publicly accessible image (PNG, JPEG, GIF, WebP).
  • For a gallery of multiple images, use $addMediaGallery[].
