  @param logoImage   * Logo image to be used in the ad. This ad format does not allow
  the creation of an image using
  the Image.data field. An image must first be created
  using the MediaService, and Image.mediaId
  must be populated when creating a {@link "ResponsiveDisplayAd"}.
  Valid image types are GIF,
  JPEG, and PNG. The minimum size is 128x128 and
  the aspect ratio must be 1:1 (+-1%).
