When pulling files over ForeignAPIRepo, the source site is what creates the thumbnails; we don't care whether we can locally produce thumbs of TIFFs. This feels a bit hacky, and may indicate we need to better refactor media handlers & file repositories. As long as the source site can produce a thumbnail image URL or a chunk of HTML to export, the local site shouldn't have to touch any of that stuff and should just be passing data through.
