Comment (by westi):

 As well as the major optimisation of an improved query here there is a
 simple optimisation we could use to improve the performance of this on
 sites with a large number of images attached to a post.

 If we switch from get_children to get_posts we can avoid calling
 update_post_cache on every attachment post for every query.
