  var PrintBand: Boolean);
  var bs : TStream; jp : TJpegImage; buff: Word;
  begin
// alinear la descripcion
QRDes.Top := DetailBand1.Height - 180;

  bs := FrmCapturaDocumentos.QDocumentos.CreateBlobStream(QDocumentosImagen,bmRead);
try
bs.Seek(0,soFromBeginning);
if bs.Read(buff,2) > 0 then
begin
  bs.Seek(0, soFromBeginning);
  case buff of
  $4D42: qmyImg.Picture.Bitmap.LoadFromStream(bs);
  $0000: qmyImg.Picture.Icon.LoadFromStream(bs);
  $0001,$CDD7: qmyImg.Picture.Metafile.LoadFromStream(bs);
  $D8FF: begin
  jp := TJpegImage.Create;
  jp.LoadFromStream(bs);
  qmyImg.Picture.Assign(jp);
