 > Hi, I'm a newcomer looking to contribute. I've been having a look at
 what changes would need to be made to implement this new feature.

 Great, glad to have you :)

 > I can't see how to add an extra instance variable to the Attachment
 model, but I think you'd have to add an extra instance variable which
 returned the file size for each image. If it's not already implicitly
 known, I'm guessing if we already have the filename then we could use the
 `filesize($filename)` function to get the size of the file.

 You might take a look at how the filesize is derived for use in the
 attachment meta box on the attachment editing screen -- the source for
 `attachment_submitbox_metadata()` is a good starting place. You'll notice
 the 'filesize' key isn't always set as part of the array returned by
 `wp_get_attachment_metadata()`, so that's a case that'll need to be
 accounted for.

 Also, take a look at `wp_prepare_attachment_for_js()`, which is where the
 filesize value would be passed to the media template, I'd think as part of
 the `$meta` array.
