A-ha, I see what you mean.

AFAIK that mode of upload separate to the image POST is not currently
supported, but it would be quite straightforward to add say support
for a header that identifies an image location for glance to retrieve
from (as opposed to just recording the external location).

Something like:

  X-Image-Meta-Retrieve-From: URI

where URI is a HTTP, S3, or Swift location that's accessible to the
glance API service.

Would that address your use-case, Gabriel?

Cheers,
Eoghan
