@UltimaterMay 05.2006 — One way:
<i>
</i>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd"&gt;

&lt;html lang="en"&gt;
&lt;head&gt;

&lt;meta http-equiv="content-type" content="text/html; charset=iso-8859-1"&gt;

&lt;script type="text/javascript"&gt;
function position(t)
{
alert('the image's TD position is: '+t.parentNode.cellIndex+"nTR position is:"+t.parentNode.parentNode.rowIndex)
}
&lt;/script&gt;

&lt;title&gt;test&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

&lt;div id="myImages"&gt;
&lt;table&gt;
&lt;tr&gt;
&lt;td&gt;&lt;img src="myimage.jpg" onclick="position(this)" width="50" height="50" alt="image"&gt;&lt;/td&gt;
&lt;td&gt;&lt;img src="myimage.jpg" onclick="position(this)" width="50" height="50" alt="image"&gt;&lt;/td&gt;
&lt;td&gt;&lt;img src="myimage.jpg" onclick="position(this)" width="50" height="50" alt="image"&gt;&lt;/td&gt;
&lt;td&gt;&lt;img src="myimage.jpg" onclick="position(this)" width="50" height="50" alt="image"&gt;&lt;/td&gt;
&lt;td&gt;&lt;img src="myimage.jpg" onclick="position(this)" width="50" height="50" alt="image"&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td&gt;&lt;img src="myimage.jpg" onclick="position(this)" width="50" height="50" alt="image"&gt;&lt;/td&gt;
&lt;td&gt;&lt;img src="myimage.jpg" onclick="position(this)" width="50" height="50" alt="image"&gt;&lt;/td&gt;
&lt;td&gt;&lt;img src="myimage.jpg" onclick="position(this)" width="50" height="50" alt="image"&gt;&lt;/td&gt;
&lt;td&gt;&lt;img src="myimage.jpg" onclick="position(this)" width="50" height="50" alt="image"&gt;&lt;/td&gt;
&lt;td&gt;&lt;img src="myimage.jpg" onclick="position(this)" width="50" height="50" alt="image"&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/table&gt;
&lt;/div&gt;

&lt;/body&gt;

&lt;/html&gt;
