Hi Sashikanth,
here is how to do it.
change
<td>$location</td>\n
into
<td><img src='$location' ></td>\n
then // to comment the useless php code.
see the changes below:
while ($row=mysqli_fetch_array($data))
{
extract($row);
$building = $row[0];
$parking_lot = $row[1];
$Number_of_Empty_Spaces = $row[2];
$Distance = $row[3];
$time_l = $row[4];
$time_h=$row[5];
$location=$row[6];
echo "<tr>\n
<td>$building</td>\n
<td>$parking_lot</td>\n
<td>$Number_of_Empty_Spaces</td>\n
<td>$Distance</td>\n
<td>$time_h - $time_l mins</td>\n
<td><img src='$location' ></td>\n
</tr>\n";
}
echo "</table>\n";
// $err=1;
//if ($img = file_get_contents("$location", FILE_BINARY))
//{
//if ($img = imagecreatefromstring($img)) $err = 0;
//}
//if ($err)
//{
//header('Content-Type: text/html');
//echo '<html><body><p style="font-size:9px">Error getting
image...</p></body></html>';
//}
//else
//{
//header('Content-Type: image/jpeg');
//imagejpeg($img);
//echo '<img src="mysqli.php?&img=' . $location . '" border="1"
height="150" width="200" alt="' . $build . '">';
//imagedestroy($img);
//}
?>
</body>
</html>
