linking images Options

[kmesz]

I finally discovered the joys of div layovers I just have one problem. I can't get my images to link.
this is my code
<div class="bg" style="position:absolute; top:594px; left:50%; margin-top:0px; margin-left:162px; height: 410px; overflow: hidden;">
<img src="http://i267.photobucket.com/albums/ii283/kmesz/davidsmypace01/DM_Page_07.jpg"/>
</div>

whenever I write <a href="http://urltothesite.com"> it makes the button disappear.
can anyone clear this up to my as to why this is happening?

Thanks!
