The following code is partialy taken from the plugin Taxonomy Images and it’s working:

function get_taxonomy_image( $atts ) {

    $atts = shortcode_atts( array(
        'image_size' => 'thumbnail',
        'id' => '',
        ), $atts );


    if( ! empty( $atts['id'] ) ) {
        $term = get_term( $atts['id'] );

        $related_id = 0;
        if ( isset( $term->term_taxonomy_id ) ) {
            $related_id = (int) $term->term_taxonomy_id;
        }

        $attachment_id = 0;
        $associations = get_option( 'taxonomy_image_plugin' );
        if ( isset( $associations[ $related_id ] ) ) {
            $attachment_id = (int) $associations[ $related_id ];
        }

        $imgsrc = wp_get_attachment_image_src( $attachment_id, $atts['image_size'] );

        return $imgsrc[0];
    }

    return 'no-id-set';
}

add_shortcode( 'sagaio-term-image', 'get_taxonomy_image' );
