Adding New <tr> when <td> increases!!

this is my code it echos images in <td>
Now,if i want it to make new <tr> if the <td> is becoming more than 3
ex:i have 6 images,using this code will show me them under eachother
but i want every <tr>to have only 3 <td> and then if the number of images increase more than 3,it make new <tr> to the rest of the images
what can i do????

$sql=mysql_query("Select * from clients");
<tr>
	  <?php do { ?>
        <td>
          <a href="client_view.php?client_images_id=<?php echo $row_Recordset1['client_images_id']; ?>"><img src="Admin/<?php echo $row_Recordset1['client_images_fotos']; ?>" width="170" height="170">          </a>        </td>
		      <?php } while ($row_Recordset1 = mysql_fetch_assoc($Recordset1)); ?>
      </tr>
