 On a site with many unattached media items (e.g. ~25,000), use of the
 {{{*_image_link}}} functions can fail.

 This is because the {{{adjancent_image_link}}} function makes a
 {{{get_children}}} call with {{{post_parent = 0}}}, causing all unattached
 media items to be returned.

 One possible optimization would be to return only IDs but that's likely to
 still fail when the unattached count is in the tens of thousands. It would
 be better to only query for the ID of the adjancent post.
