[wp-hackers] Wordpress Media Uploader Use in a Plugin

[Eric Andrew Lewis]

In the options hash you pass to wp.media, set `multiple` to `true` for
multi-select.

In your on `close` event handler, you have full access to an attachment
model's attributes, including the `size` attribute, which includes various
image sizes.
