how to avoid warning notice "taxonomy does not have image support"?

Hello,
Thank you very much for this excellent plugin. Works fine with WP3.5.1.

I want to automate the display of images for all terms of all taxonomies that have an image associated. Unfortunately your plugin raise a warning for taxonomies for which taxonomy-images has not be activated.

Could you please tell me how to hide this warning as it is displayed on the blog in public… or add a test function to your code “taxonomy-images-is-active-for-taxonomy”? As it is a warning and not an error I cannot try/catch it.

For info / other users my code for displaying all terms images is below, terms with no images get displayed as text links (to be put in your template functions.php.

function custom_taxonomies_terms_links_images() {

  	$id = get_the_ID();
	$post_type = get_post_type($id);
	$taxonomies = get_object_taxonomies($post_type);
	$out_images = $out_texts = array();
	foreach ($taxonomies as $taxonomy) {
		//if ($taxonomy == 'post_format') //internal WP3.1+ taxonomy, skip.
		//	continue;
		//next filter shows notice on blog if images not activated for taxonomy
		$terms = apply_filters( 'taxonomy-images-get-the-terms', '', array(
	       'taxonomy'     => $taxonomy,
	       'post_id' => $id
	    ) );
    	// if the above rises a warning, then images are not activated for this taxonomy, then populate terms with:
        //    $terms = get_the_terms( $id, $taxonomy );        

	    if ( !empty( $terms ) ) {
			foreach ( $terms as $term )
				if (!empty($term->image_id)) {
					$out_images[] = '<li class="taxonomy-image"><a href="' . esc_url( get_term_link( $term, $taxonomy ) ) . '" title="'.$term->name.' ('.$taxonomy.')">' . wp_get_attachment_image( $term->image_id, 'detail' ) . '</li>';
				}
				else
					$out_texts[] = '<a href="' .get_term_link($term->slug, $taxonomy) .'">'.$term->name.'</a>';
		}
	}
	if ($out_texts)
		$out_images[] = '<li class="taxonomy-text">'.join( ', ', $out_texts).'</li>';  

	return '<ul class="taxonomy-images-the-terms">'.join( '', $out_images).'</ul>';
}

simply call it with <?php echo custom_taxonomies_terms_links_images(); ?> wherever the loop is displaying the categories of a post, for instance.
