I'm using Dropbox Javascript SDK.
In documentation, (http://dropbox.github.io/dropbox-sdk-js/global.html#FilesSearchMatch)
`FilesSearchMatch` could have `FilesFileMetadata` and, `FilesFileMetadata` could have `media_info` optionally.
But all my '.jpeg' photos which were taken from cameras(many kinds) have no `media_info` field in `metadata`.
Is it right?
