use assign instead and create your tmpimage, like

procedure TForm1.BitBtn1Click(Sender: TObject);
var
  imgTemp: TBitmap;
begin
 imgTmp := TBitmap.Create;
 try
   imgTemp.Assign(Image1.Picture.Bitmap);
   Image1.Picture.Bitmap.assign(Image2.Picture.Bitmap);
   Image2.Picture.Bitmap.assign(imgTemp);
 finally
   imgTmp.free
 end;
end;
