Taxonomy image with multiple vocabularies!!!

Hi friends,
i have more vocabularies (3) attached to node and i have difficutl to use Taxonomy image with it.

if i have only a vocabulary there isn't any problem with this function inserted in node.tpl:

	foreach (taxonomy_node_get_terms($node->nid) as $term) {
    if ($image = taxonomy_image_display($term->tid)) {
      print $image;
    } else {?>
	<span class="taxonomy"><?php print $terms?></span>
	<?php
	}
	}
	?>

but when i have more vocabularies the above function doesn't work well...she show all terms attacched at node (with and without image).

pls help me.....
sincerly..
Max
