After rereading the CC-BY legal code it does appear you (and others
who made this point) are correct, and I was quite mistaken about the
strength of the CC-BY license.
http://creativecommons.org/licenses/by/3.0/legalcode
"You may Distribute or Publicly Perform the Work only under the terms
of this License."

Indeed it seems CC-BY is already the "weak copyleft" I was thinking
CC-BY-SA is... CC-BY is much stronger than I realised. I thought CC-BY
just meant "include a byline with my name".

I am probably not the only one who had this impression, because the
Wikimedia Commons summary as it stands is deeply misleading.
http://commons.wikimedia.org/wiki/Template:Cc-by-3.0

How embarrassing.

So, is this understanding correct: using CC-BY, a reuser could create
a derivative work that was not freely licensed, but provide info that
the source image was CC-BY (and provide link), and that would be
acceptable? Is that true?

Well... now I think shoring up CC-BY-SA to be a strong copyleft is a
good idea, since Greg is correct...if we can correct the
misperceptions of people like me then I don't see why this idea
wouldn't receive widespread support.

cheers,
Brianna
