    this line is wrong:

     echo "<td>" . $row ['<img src="', $dir, '/', $file, '" alt="', $file, '" />'] . "</td>";

    why not just, also why are you using $row[] to display the image, $row is meant for retrieving the values in your database corresponding to the table field. $row[‘table field’];

    echo '<td>';
echo '<img src =';
echo $dir."/".$file;
echo  '/>';
echo '</td>';

    also try

    $dir = "images/";
