Shuffle lets you:
<ol>
<li>Attach an item (Image, Audio, Video) to anything (Post, Page, Custom Post Type, another Attachment)!</li>
</ol>
Use these functions in your Theme to get your re-ordered Media:
<pre><code><?php
//In the Loop:
get_images();

//Outside of the Loop:
get_images( get_the_ID() );

// Audio
get_audio();

// Video
get_video();

?>
</code></pre>

Note: Obsolete since WordPress 4.4
<a href="https://core.trac.wordpress.org/ticket/32230" rel="nofollow ugc">This feature has been added into the core of WordPress 4.4</a>. You can now export your attachments by going to Tools->Export and select ‘Media’ as the export type.
Original Description
WP Attachment Export allows you to export your media library into a WordPress eXtended RSS or WXR file. You can then use the Tools->Import function in another WordPress installation to import the media library.

WP Attachment Export

works perfectly.

Exports only posts of type 'attachment', i.e. your media library
