Using HTML, you would do:
?>
<td align="left">
<font color="black" face="arial" size="-1">
<a href="http:<? echo $row["map"]; ?>">
<img src="<? echo $row["map"]; ?>">
</a>
</td>
<?
Although you may have to think about the $row[map], as currently, you are trying to output the link address, and image address from the same field in your database.
