Sufficiently large image uploads into Glance from Horizon can cause timeout errors, since the image upload needs to complete before the view can render, and such activities can cause browser timeouts. Since the webserver already has the file, and close-to-open semantics should prevent cleanups from losing any data, just send it in a background thread, the same way as if you told Horizon to fetch it from a remote location.
