HTML idiot

OK, so Im not a HTML kind of guy..

My sidebar has a pic in the text widget, I want it to link to Obama’s site.
I am pretty sure I am suppose to use but am lost.

this is what Ive got in the widget:
table width=”175″ border=”0″>
<tr>
<td><img src=”https://kielhurn.com/wordpress/wp-content/uploads/2008/07/dsc02405.jpg”/&gt;

</tr>
</table>

how to make the picture link to a site and where to add the code?
