[themes] Contemplate theming

[Mark Hope]

Hi,

I'm having difficulty achieving some output using the Contemplate 
module - hope somebody can help out.

I'm using CCK, imagecache and contemplate to produce a 'case study' 
content type. The teaser view page has been customised using 
Contemplate module, inserting a thumbnail image created by Imagecache 
module (namespace of 'focuson').

The code is outputing markup for the image thubnail even if the 
imagefiled ($field_focus_on_thumb) is empty.
How do I create an array for only items that have the used the 
imagefiled ($field_focus_on_thumb)?

code:

<?php foreach ((array)$field_focus_on_thumb as $item) { ?>
<div class="field field-type-image field-field-focus-on-thumb">
<div class="field-items">
<div class="field-item">
<img src="<?php print $GLOBALS['base_url'] 
?>/files/imagecache/focuson/<?php print $item['filepath'] ?>" 
alt="<?php print $item['alt'] ?>" title="<?php print $item['title'] 
?>">
</div>
</div>
</div>
<?php } ?>

<div class="field field-type-text field-field-teaser-text">
<div class="field-items">
<?php foreach ((array)$field_teaser_text as $item) { ?>
<div class="field-item"><?php print $item['view'] ?></div>
<?php } ?>
</div>
</div>
<div class="links"><a class="read-more" href="/<?php print $path 
?>">read more</a>&nbsp;&raquo;</div>

Thanks
Mark
