Insert Image in step3 checkout

[pschievink +]

Hi guys,

I've tried to put a image next to the extra options section but for some reason it won't show..

Can someone give a hint on how to?
I want to put it in the red square but for some reason it won't show...
I've tried to put a section in the css but no result...

css code:
/*Pedegree styles */
#pedegree
{
position:absolute;
float:right;
width:100%;
height:450px;
}

And this in step 3:

<div class="clear"></div>

{$extra_listing_fields}

{modulehook function="tpl_addlisting"}
<img class="pedegree" src="http://paardenverkoop.net/images/stamboomvoorbeeld.JPG">
<div id="optResponse"></div>
</fieldset>
