Hi Paul,
Yes, you can download an image file using a URL like this:
https://images.joyent.com/images/<IMAGE_UUID>/file
https://images.joyent.com/images/ab3db4c0-31ac-11e5-8856-43e56a8e4285/file
Many thanks.
Unfortunately, I don't think that supports resuming with curl's "-C -"
flag...
That's not a problem. A method that works here is the download the
entire
image(s) to my hosting ISP, split them into smaller chunks, then rsync
those
across, repeating the rsync if my connection goes AWOL. It works well.

This is an example of a failed download using imgadm import. To my
mind, imgadm should simply exit when it decides to abort the
download and avoid needlessly ploughing on with checksums which are
obviously going to fail.

Granted, this is a result of my sometimes less than stellar
broadband connection, but imgadm should really deal with this in a
cleaner fashion (IMHO).
A "nice to have" feature here would be the ability to continue a
failed download.
Alternatively, is there a means of deriving the URL(s) for the
components of a given image and downloading manually, e.g. via 'curl
-C' to handle download failures?
