In my book the low and high resolution images are the same work. The
license is obviously worded so that all versions of a work (but not
derivative works created by the licensor) are covered by the license.
All versions or editions of a work are thus covered by the grant in
section 3 (license grant). So - yes - if you offered a low resolution
image under BY-SA, the high resolution image (being the same work) would
also be available under the same terms. That outcome might not be
intended by some (many?) licensor's but it follows from the language of
the license. Btw I seem to recall that this issue (or a very similar
one) has been discussed (to some length) on this list - can't remember
how long ago.
