Sorry for being vague.
Basically:
<div style="width:100%; text-align:center; padding-top:10px; font-size:10px;"><div class="tborder" style="width:560px; margin:auto; padding:1px; position:relative; text-align:left;"><img style="position:absolute; top:-20px; left:-17px; z-index:100;" src="http://www.dragonflycave.com/sprites/gen4/dp/012f.png">
<div class="thead" style="padding:3px 3px 3px 55px; margin-bottom:1px;">A Heading</div>
<div class="alt1" style="padding:3px;"><span style="width:48px; height:20px; float:left;"></span>Text in the box</div>
</div>
</div>
The bolded bits are the values you might want to tinker with. First it's the width of the box, which you can decide for yourself; then there's how far up and left you want to shift the image from the top left corner of the box; then there's the image URL; then there's the increased left padding on the heading in order to shift the text so that it doesn't go under the image, which you should experiment with until it looks right; and finally there's the empty float that makes the main text not go under the image and how tall and wide that should be (again, experiment until it looks right).
