Adding an Image link to sidebar

Hello,

I am trying to add an image link to my side bar.
I’d like it to link to http://www.engineroomedit.com.

Currently I have this code in my sidebar.

<div class="boxes">
<h2>Where I Work</h2>
<a href="http://validator.w3.org/check/referer" "#" class="ads"><img src="http://www.five13.net/wordpress-NEW/wp-content/uploads/engineroom.gif" border="0" alt="Ad" /></a>
</div>

I tried a few different tactics and the link shows up as text.
