 No, there aren't; you do a GET request to the endpoint. The oEmbed
 provider is the one responsible for returning something useful.

 > - '''WP_Http''' - The are numerous possibilities for how a server might
 be able to process an HTTP call, and implementing this class is hard.

 When you use WP_Http, you want to make a HTTP request; regardless of the
 transport the server employs, the effect of the request is the same: you
 get back a response object.

 In contrast, with the proposed get_attached_images() function, how the
 images are associated to the post ''does'' affect what you can do with
 them. For example, you won't be able to manipulate an 'external' image the
 same way you could an 'attached' one.

 Therefore, it's a leaky abstraction.
