Opening a .jpg file

<tr >
 <td >" . $row['serialno']."</td>
 <td  >" . $row['lotno']."</td>
<td  >" . $row['address01']."</td>
<td  >" . $row['graphic01']." </td>
</tr>

I have a table like where the last column is a .jpg file.

I would like the ,jpg file to open if someone clicked on it.

How is this done?
