HI There, I had the same question and I wrote my own code so I thought I would share for others.
This is to obtain the images for my custom taxonomy “service” and print them out within my custom get_terms() loop.
$taximages = get_option( 'taxonomy_image_plugin' );
$services = get_terms(array(
'taxonomy' => 'service',
'hide_empty' => false,
));
foreach($services as $service) {
$link = get_term_link(intval($service->term_id),'service');
echo "<h2><a href=\"{$link}\">{$service->name}</a></h2>";
$taximageid = $taximages[intval($service->term_id)];
echo wp_get_attachment_image ($taximageid, 'medium');
}
Hope it helps ??
