Use-cases for this:

1) Browsers could let the user download the full-size image instead of the
thumbnail when they click "Save Image As..." or similar.  (Not too risky if
it's a separate context menu option; if the author inadvertently or
deliberately specifies something that's not actually a full-size equivalent,
the user can figure it out and go back to get the thumbnail.)

2) Browsers could download the full-size image instead of the thumbnail if
they're outputting to a high-resolution medium, such as print or an iPhone 4
display.  This use-case is shakier, because a) authors who want to prevent
redistribution of their pages could put fake full-size links to prevent users
from printing, and browsers would have to implement heuristics to stop this;
and b) the full-size image might take up far too much bandwidth to be worth it.

One example of a site that could use this extensively is Wikipedia.  Many
articles have pictures, and practically all of those are thumbnails of much
higher-res images.  There are probably lots of users who download the low-res
version because they don't realize the high-res one exists (although that's
just a guess, there's no way to tell).
