Image is not displayed
<p>I am trying to display records with Images. I carefully named each image (1.png, 2.png, etc.) and placed them in the root folder. It should represent PRIMARY KEY of the record that I want to display.
Here is the code: </p>

<pre><code>while($row = mysql_fetch_array($result))
  {
  echo "&lt;tr&gt;";
  echo "&lt;td&gt;" . $row['DeptNo'] . "&lt;/td&gt;";
  echo "&lt;td&gt;" . $row['DeptName'] . "&lt;/td&gt;";
  echo "&lt;td&gt;" . $row['Location'] . "&lt;/td&gt;";
  echo '&lt;td&gt;&lt;img src="'. $row['DeptNo']. '.png' . '"&gt;&lt;/td&gt;&lt;/tr&gt;';
  echo "&lt;/tr&gt;";
  }
echo "&lt;/table&gt;";
</code></pre>

<p><strong>Please note the Column ID is just for the  representation view, the real column is still DeptNo</strong></p>

<p>However, when I run it the images are not displayed. Where did I go wrong? 
<img src="http://i.stack.imgur.com/AQ3Jr.jpg" alt="enter image description here"></p>
