Sorry for late reply.

O.k., if you want to to have a thumb displayed, if no picture is attached, then you have to change the code in threadbit_gallery:

Find

<td width="170" height="170" align="center">
			     <if condition="$displaythumbs">
			     	<a HREF="attachment.php?attachmentid=$thread[attachmentid]">
			          	<img src="attachment.php?attachmentid=$thread[attachmentid]&stc=1&thumb=1" border=0 align="center">
			        </a><br>
			     <else />
			        <img src="$stylevar[imgdir_misc]/nothumb.gif" width=75 height=56 border="0">
			     </if>
<br />
</td>

and replace it with:

<td width="170" height="170" align="center">
			     <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 align="center">
			        </a><br>
			     <else />
			        <img src="$stylevar[imgdir_misc]/nothumb.gif" width=75 height=56 border="0">
			     </if>
</if>
<br />
</td>

And don't forget to upload an :gif-File called "nothumbs.gif". That should do it.
