    Default Usage
    As the tag does not display the permalink, the example uses the PHP echo command.

    <?php 
    $attachment_id = 1; // ID of attachment
    $attachment_page = get_attachment_link( $attachment_id ); 
    ?>
    <a href="<?php echo esc_url( $attachment_page ); ?>"><?php echo get_the_title( $attachment_id ); ?></a>

    Display attached images and titles as a list
    To display the images attached to a certain page and display them as a list of bullets you can use the following:

    <ul>
    <?php if ( have_posts() ) : while ( have_posts() ) : the_post();    
    
    	$args = array(
    		'post_type'   => 'attachment',
    		'numberposts' => -1,
    		'post_status' => null,
    		'post_parent' => $post->ID
    	);
    
    	$attachments = get_posts( $args );
    	if ( $attachments ) {
    		foreach ( $attachments as $attachment ) {
    			echo '<li>';
    			the_attachment_link( $attachment->ID, true );
    			echo '<p>';
    			echo apply_filters( 'the_title', $attachment->post_title );
    			echo '</p></li>';
    		}
    	}
    endwhile; endif; ?>
    </ul>
