How to hide image when insert into post?

I create slideshow in single-post and check if have only 1 image is show 1 image, but if have images it will show slide then can click button prev and next.

Problem is:
I don’t want to show image or exclude image from post content in slideshow when choose insert into post.

This my code:

<?php while(have_posts()) : the_post(); ?>
	<?php

		// Check single post have attachment image if not use thumbnail
		$thumb_ID = get_the_post_thumbnail( $post->ID );
		$images = get_posts(array(
			'post_parent' => $post->ID,
			'post_type' => 'attachment',
			'numberposts' => -1,
			'post_mime_type' => 'image',
			'exclude' => $thumb_ID,
		));

		if (count($images) > 1) {
			echo '<ul id="mycarousel" class="jcarousel-skin-tango">';
			foreach( $images as $image ) {
				$attachmenturl = wp_get_attachment_url($image->ID);
				$attachmentimage = wp_get_attachment_image_src( $image->ID, 'loop_image');
				echo '<li><img src="' . $attachmentimage[0] . '" /></li>';
			}
			echo '</ul>';
		} else {
			echo '<div id="entry_image">';
				the_post_thumbnail('loop_image');
				echo $images;
			echo '</div>';
		}

		if($image != '') {
			echo '<div id="big_slide_control">';
			echo '<a href="" id="big_slide_prev"></a><a href="" id="big_slide_next"></a>';
			echo '</div>';
		}
	?>
<?php endwhile; ?>
