How to display certificate images with the uo_learndash_certificates shortcode

Hi there,

I modified a function to add a new shortcode parameter to show certificate images rather than titles.

The new parameter is show-images and can be set to true or false and defaults to false.

I also commented out a couple of seemingly useless lines for setting $quiz_title_fallback and $quiz_title variables which seems to be unused.

I forget exactly how to post code on here but hopefully this works.

The function starts at uncanny-learndash-toolkit/src/classes/show-certificates-shortcode.php line 77:

	/**
	 *
	 *
	 * @static
	 *
	 * @param $atts
	 *
	 * @return string
	 */
	public static function learndash_certificates( $atts ) {

		if ( ! is_user_logged_in() ) {
			return '';
		}

		if ( isset( $atts['class'] ) ) {
			$class = $atts['class'];
		} else {
			$class = 'certificate-list-container';
		}

		if ( isset( $atts['title'] ) ) {
			$title = $atts['title'];
		} else {
			$title = '';
		}

		if ( isset( $atts['no-cert-message'] ) ) {
			$no_cert_message = $atts['no-cert-message'];
		} else {
			$no_cert_message = esc_html__( 'Complete courses to earn certificates', 'uncanny-learndash-toolkit' );
		}

		if ( isset( $atts['show-image'] ) ) {
			$show_image = boolval($atts['show-image']);
		} else {
			$show_image = false;
		}

		$certificate_list = '';

		/* GET Certificates For Courses*/
		$args = array(
			'post_type'      => 'sfwd-courses',
			'posts_per_page' => - 1,
			'post_status'    => 'publish',
			'orderby'        => 'title',
			'order'          => 'ASC',
		);

		$courses = get_posts( $args );

		foreach ( $courses as $course ) {

			$certificate_id     = learndash_get_setting( $course->ID, 'certificate' );
			$certificate_object = get_post( $certificate_id );

			if ( ! empty( $certificate_object ) ) {
			    if($show_image) {
				    $certificate_img = get_the_post_thumbnail($certificate_id, array(175, 175));
				    $certificate_link  = learndash_get_course_certificate_link( $course->ID );

				    if ( $certificate_link && '' !== $certificate_link ) {
					    $certificate_list .= '<a target="_blank" href="' . $certificate_link . '">' . $certificate_img . '</a>';
				    }
			    } else {
                    $certificate_title = $certificate_object->post_title;
                    $certificate_link  = learndash_get_course_certificate_link( $course->ID );

                    if ( $certificate_link && '' !== $certificate_link ) {
                        $certificate_list .= '<a target="_blank" href="' . $certificate_link . '">' . $certificate_title . '</a><br>';
                    }
			    }
			}

		}

		/* GET Certificates for Quizzes*/
		$quiz_attempts = self::quiz_attempts();

		if ( ! empty( $quiz_attempts ) ) {

			$quiz_attempts = array_reverse( $quiz_attempts );

			foreach ( $quiz_attempts as $k => $quiz_attempt ) {

				if ( isset( $quiz_attempt['certificate'] ) ) {
					$certificateLink     = $quiz_attempt['certificate']['certificateLink'];
					//$quiz_title_fallback = ( isset( $quiz_attempt['quiz_title'] ) ) ? $quiz_attempt['quiz_title'] : '';
					//$quiz_title          = ! empty( $quiz_attempt['post']->post_title ) ? $quiz_attempt['post']->post_title : $quiz_title_fallback;

					if ( ! empty( $certificateLink ) ) {

						$meta               = get_post_meta( $quiz_attempt['post']->ID, '_sfwd-quiz', true );

						$certificate_object = get_post( $certificate_id );

						if($show_image) {

						}

					}

		$certificate_list = apply_filters( 'certificate_list_shortcode', $certificate_list );

		if ( '' === $certificate_list ) {
			$certificate_list = $no_cert_message;
