  // 1st parameter: name of picture. Allows to store additional text information
  //  together with image. There is no predefined meaning of this
  //  parameter. May be in future this string will be shown as a hint.
  // 2nd parameter: image. TBitmap, TIcon, TMetafile, etc.
  // 3rd parameter: index of paragraph style (-1 to continue paragraph)
  // 4th parameter: vertical align of image.
  //  In current version RichView understands two options:
  //  - rvvaBaseline: align bottom of image to base line of text;
  //  - rvvaMiddle: align middle of image to base line of text;
