Comment (by mikeschroder):

 As noted in the Slack mention above, @joemcgill and I met about this
 ticket a bit at Loopconf regarding what would be necessary for the first
 steps here.

 They look something like:
 - Improve JS handling of http error codes and body, to provide more
 detailed error messages
 - Save progress of meta/`multi_resize` during creation of the intermediate
 images (with save basic meta before starting resizing process)
 - Resume `multi_resize` without re-uploading the file

 I've got a pretty good idea of what the latter two will look like, but any
 insights of the JS handling -- in particular, why we're not surfacing any
 error details -- would be appreciated. I remember that there were
 technical challenges (rather than deciding the information was not
 helpful) involved in resolving this, but do not remember all of the
 background.

 I don't think it necessarily needs to happen in this order, as making it
 so that thumbnail resizing resumes in any form will help more users be
 successful in getting their images uploaded (and eventually not having the
 HTTP Error show up).
