Try this, open the file index.main.php and change the line 94

<div class="headerphoto">
  <object type="application/x-shockwave-flash" data="img/flash.swf" width="770" height="200">
    <param name="movie" value="img/flash.swf">
    <param name="wmode" value="transparent">
  </object>
</div>

You may also need to change the class headerphoto in style.css, line 216.

/* header photo */
.headerphoto {
	margin: 0 auto;
	width: 770px;
	height: 200px;
	padding: 15px 10px 10px 10px;
	background: #FFF url('img/headerphoto.jpg') no-repeat center;
}

Thank you so much! It worked.

I have a question about your Flash tag widget. I tried adding it to my footer and page top but it''s not showing. Also, where can I insert the words that I need?
