I seem to be a bit confused right now :P
suppose I have a template:
<table width="100%" border="0" cellpadding="0" cellspacing="3"> 
<tr> 
   <td> 
      <table width="100%" border="0" cellpadding="1" cellspacing="3"> 
      <tr> 
         <td valign="top" colspan="2" class="wsheader"> 
            {lst.title_id;block=row;htmlconv=no;encaps=2} 
         </td> 
      </tr> 
      <tr> 
         <!-- QUESTION IS ABOUT THIS --> 
         <td width="100" valign="top" nowrap class="wsback1"> 
            <a href="/data/article/images/{lst.image;htmlconv=no}"> 
               <img src="/data/article/images/thumbnails/{lst.image_thumb;htmlconv=no;friendb=img}"></a> 
         </td> 
         <!-- upto here --> 
         <td width="90%" height="50" valign="top" class="wsback2"> 
            Omschrijving<br/> 
            {lst.descr_id;htmlconv=wsp;.} 
         </td> 
      </tr> 
      </table> 
   </td> 
</tr> 
<tr class="wsback1"> 
   <td>Er is geen artikel gevonden.{lst;block=row;nodata}</td> 
</tr> 
</table> | 
 
and in the snippet from that code marked with the comments I want the image to be replaced by text 'click here for larger image' when the var lst.image_thumb is empty
for some reason I cannot get it done :S
Think I've been at it too long, approaching the problem from the wrong direction, anybody a new view for me?? ;)
