I've added the code just below the title but within the message element. It'll be in form of a background rather than an image. Try:

Find:

  <!-- message -->
  <div id="post_message_$post[postid]">

Add after:

  <div class="postbitimg"></div>

Main CSS in Additional CSS Definitions add:

.postbitimg {
  float:right;
  display:block;
  width:100px;
  height:30px;
  margin:0 0 10px 10px;
  padding:3px;
  border:1px solid #000000;
  background:#ffffff url(/img/path) no-repeat top left;
  }

It's important to define the width and height settings for float blocks. Edit out the variables you don't want and change the values for each to suit your needs. The padding applies inside the element while the margin applies outside it.

I hope this is workable for you. If not just holler me back. Though, I may respond tomorrow since it's about to be party time!
