Add a thumbnail to a get_categories query

<?php
$cats = get_categories(‘orderby=count&number=5&order=asc’);
foreach ((array)$cats as $cat) {
$catdesc = $cat->category_description;
echo ‘‘?><?php ciii_category_archive_image($cat); ?><?php ‘‘;
}
?>

Is what I am doing right now but the image doesn’t show… I am sure this is something stupid simple…. help?
