Get image by term ID

[rilwis]

I want to get the image of a term (not the current queried term) to show outside the loop or taxonomy page template, like in menu, sidebar, etc. I found that there's no such filter for this purpose.

Right now, I have to use this solution, but I hope you can add the filter for getting image for a specific term in near future:

$term = get_term( $term_id, $taxonomy );
$tt_id = 0;
if ( isset( $term->term_taxonomy_id ) )
    $tt_id = (int) $term->term_taxonomy_id;

$associations = taxonomy_image_plugin_get_associations();
$image = '';
if ( isset( $associations[ $tt_id ] ) ) {
    $attachment_id = (int) $associations[ $tt_id ];
    $image = wp_get_attachment_image( $attachment_id, $size );
}

Thanks @rilwis for sharing the solution, it works nicely when wrapped in a function!

Thank you for the code.

I made a function to get the attachment id.

/**
 * Get Taxonomy Image ID
 *
 * Uses the 'Taxonomy Image' plugin.
 *
 * @param $term int|WP_Term|object
 * @param $taxonomy String Taxonomy name that $term is part of.
 * @return int|fase The attachment id on success. False when term does not exist or no image found.
 */
function my_get_taxonomy_image_id( $term, $taxonomy = '' )
{
	if ( ! function_exists( 'taxonomy_image_plugin_get_associations' ) ) 
	{
		return false;
	}

	if ( ! taxonomy_image_plugin_get_associations( $term_id ) ) 
	{
		return false;
	}

	$term = get_term( $term, $taxonomy );

	if ( ! $term || is_wp_error( $term ) ) 
	{
		return false;
	}

	$tt_id = 0;

	if ( isset( $term->term_taxonomy_id ) )
	{
	    $tt_id = (int) $term->term_taxonomy_id;
	}

	$associations = taxonomy_image_plugin_get_associations();

	if ( isset( $associations[ $tt_id ] ) ) 
	{
	    return (int) $associations[ $tt_id ];
	}

	return false;
}
