How To Place An Iframe Over An Image?

I'd like to place an image under my iframe, but i've pieced together some code and it doesn't appear to be exactly right. The iframe contains text and has a transparent background

Solution 1:

<img src="http://southwestarkansasradio.com/images/onair995.jpg"></a><br>
<img src="http://southwestarkansasradio.com/images/playerbackground.jpg" style="z-index:  -1"/>
<div style="position:absolute;left:0px;top:0px;font-size: 32px">
  <iframe width="316" height="216" src="http://southwestarkansasradio.com/NowPlaying.html" border="0" frameborder="0" allowTransparency="true">
      Your browser does not support inline frames.</iframe>
</div>

You have 'display:none' on the div tag that contains the iframe. I tested the above code and it works as you have explained is should.
