How do I make a PNG resource?

Example text file (named myres.rc):

MYPNG RCDATA mypng.png

Added to project:

{$R 'myres.res' 'myres.rc'}

Example of loading at runtime:

uses
  PngImage;

var
  Png: TPngImage;
begin
  Png := TPngImage.Create;
  try
    Png.LoadFromResourceName(HInstance, 'MYPNG');
    Image1.Picture.Graphic := Png; // Image1: TImage on the form
  finally
    Png.Free;
  end;
end;
