I have pictures in a database and i want to read it out and display it as a picture. However i get strange long charakters as result.

benim kod:

/** ensure this file is being included by a parent file */
defined( '_VALID_MOS' ) or die( 'Direct Access to this location is not allowed.' );
 // assemble query
$query = '
    SELECT *
    FROM artikel
';

$database->setQuery($query);
if ( !$database->query() ) {
echo "<script type='text/javascript'>
         alert('".$database->getErrorMsg()."');
      </script>";
} else {
$rows = $database->loadObjectList();
}
echo '<table>';
foreach ($rows as $rowi)
{

echo '<tr><td>'.$rowi->Artikelname.'</td>';
echo '<td>'.$rowi->Stueckpreis.'</td>';
echo '<td>'.$rowi->Gewicht.'</td>';
echo '<td>'.$rowi->Lagerstand.'</td>';
echo '<td>'.$rowi->Aenderungsdatum.'</td>';
echo '<td><img>'
.$rowi->Foto.
echo'</img></td></tr>';


}
echo '</table>';
?>
