Get image of category parent?

Well, one step forward. I switched to this…

<?php if (is_category()) { ?>
			<?php print $image_url = apply_filters( 'taxonomy-images-list-the-terms', '', array(
		    'after'        => '</div>',
			'after_image'  => '',
			'before'       => '<div class="header-category-image col-full">',
			'before_image' => '',
			'image_size' => 'full'    ) );?>
		<?php } ?>

Now the only issue is that the image won’t show up on Single Posts – any solutions out there for that? Seems everyone has the same hurdle with that.

If I want the image I assigned to a category to appear on a single post (that lives in that category) do I need to find a different way to accomplish that than this plugin?

Hi Blake, there is a quick & dirty way to get the image associated to a certain term (not the actually queried term) with this plugin: all associations are kept in an array, as a wp option, so you can get the entire array just using

$associations = get_option( 'taxonomy_image_plugin' );

Every array element has the term_id as key and the attachment id as value; so we can write a function to get the image associated to a specific term ID, like this one:

if ( !function_exists( 'get_term_image' ) ){
	function get_term_image($args=array()) {
		$defaults = array (
			'term_id' => 0,
			'size' 	=> 'thumbnail',
			'classes' => 'wp-attachment term-image'
		);
		$term_img=false;
		// Parse incoming $args into an array and merge it with $defaults
		$args = wp_parse_args( $args, $defaults );
		// OPTIONAL: Declare each item in $args as its own variable i.e. $type, $before.
		extract( $args, EXTR_SKIP );
		if ( $term_id > 0) {
			$associations = get_option( 'taxonomy_image_plugin' );//check tax images created by plugin Taxonomy Images
			if ( is_array( $associations ) && count ($associations) ){
				if ( isset($associations[$term_id]) ) {
					$attachment_id=$associations[$term_id];
					$term_img=wp_get_attachment_image( $attachment_id, $size, false, array( 'class'	=> $classes ) );
				}
			}
		}
		return $term_img;
	}
}

Then you can get the html tag of the image associated with a term id, like this:

$args=(array(
	"term_id" => $my_term_id,
	"size" => "my_custom_size_or_one_of_small_medium_large",
	"classes" => "class1 class2 class3"
));
$image = get_term_image($args);
