How to print all images stored in a file Directory?

I have been trying for a day now to print all the images stored in a directory, however at the minute i can only get one to appear.

could anyone point me in the right direction?

function wptuts_setting_logo_preview() {
	$wptuts_options = get_option( 'theme_wptuts_options' ); 
    $user_id = get_current_user_id();
	$files = glob('wp-content/uploads/'.$user_id.'/*');
?>
    
	<div id="upload_logo_preview" style="min-height: 100px;">
		<img style="max-width:100%;" src="<?php echo esc_url( $wptuts_options['logo'] ); ?>" />
	</div>
	<?php
}
 ?>
