Yep -- your guess is correct.  I'm surprised that it isn't in the 4.x
spec; I suspect that it was supplanted by an equivalent CSS option.  I
*think* it is documented in the HTML 3.2 spec.  All browsers I know of
support it.  Basically the browser shows the lowsrc image first (or
only) so something is visible, and then when the final image is loaded
you show that.  If the browser knows that it has a fast connection to
the target site, it can skip showing the lowsrc version entirely.
