Setup Attachments for specific page-template?

Setup Attachments for specific page-template (like, template-about.php) ?

How can I do that?

If you want to limit a attachments instance to a single page, the _attachmentslocation{myinstance} may help you:

function my_attachments_location_limit( $val )
{
    global $post;

    // the post ID is 13 and you only want this instance to show up there
    return ( $post->ID == 13 ) ? true : false;
}

add_filter( 'attachments_location_my_attachments', 'my_attachments_location_limit' );

You can have your callback be as elaborate as you'd like, using any attributes WordPress has to offer at runtime.
