Signature question...

[Mythotical]

Ok I have customised the signature on my site to show a certain field if its filled out, field19 which is forum stats image. Only problem is my members can view it but the guests can't view it.

Here is the code:

<if condition="$post['signature']">
<!-- sig -->
<div>
<center>_________________________</center><br />
$post[signature]
</div>
</if><br />

<if condition="$post['field19']">
<div>
<center>_________________________</center><br /></if>
<if condition="$post['field19']">
<center>
<table cellpadding="3" cellspacing="0" border="1">
<tr>
<td>
<img src="$post[field19]">
</td>
</tr>
</table>
</div>
<!-- / sig -->
</if></center>

I could use any help at this point as I had someone request that I allow guests to view this field in my signature.

Thanks in advance and cheers
