Found it...it was in the original thread...if you don't have a default icon already set under Admin CP, post this instead of the stock template change:

<!-- Start: idolpx and dechevious Thumbnail in Forum Display Hack - 20041220 -->
<if condition="$show['threadicons']">

<td class="alt2" align="center" valign="middle">	
<if condition="$displaythumbs">
			     <if condition="$thread['attachmentid']">
			     	<a HREF="attachment.php?attachmentid=$thread[attachmentid]">
			          	<img src="attachment.php?attachmentid=$thread[attachmentid]&stc=1&thumb=1" border=0>
			        </a>
			     <else />
			        <img src="images/clear.gif" width=75 height=56 border="0"></if>
			 			<else /><if condition="$show['threadicon']">
<img src="$thread[threadiconpath]" alt="$thread[threadicontitle]" border="0" /></if></td>
	</if>
</if>
