Image Show using lightbox on hover as refrence stored in MYSQL

Hi, I have stored 800 images in root/Images and store link in DB for reference along with another information. There is a search box through which I get all the info. For viewing images I used <a href=".$row['image']." target=_blank>".$row['ch']."</a> Ch value is click here to view.
Now I want that specific image in light box in same window. How its possible?
Here is my comple code.

<form action="sims_search_view2.php" method="post">

<input type="text" value="Enter Site ID" name="a" class="textfield_effect" maxlength="30" onfocus="this.value=''">
<input type="submit" style="width: 200px;
	height: 20px;
	cursor: pointer;
	border: none;
	margin-left:0px;
	background: transparent url(/images/sims_search_button.jpg) no-repeat 0 0;" value=""/>
</form>	</td>
</tr>

        </table>
<div>
  <?
  $con = mysql_connect("localhost","root","");
   if(!$con)
     {
     die('Could not connect: ' . mysql_error());
    }
   mysql_select_db("onm", $con);


 $ID=$_POST['a'];
 


$result = mysql_query("SELECT * FROM `info` WHERE code=$ID ");
 
 while($row = mysql_fetch_array($result))
  {
  


//$form=<<<POST
