The link for the GIANT tiff file is:
http://lroc.sese.asu.edu/data/pr/tiff/wac_nearside.tif

You probably used the link to the smaller one
that I posted for people that wanted to see the
picture but did not want to download the whole
549 Mb.

Took me 48 minutes, but they were feeding it
slowly. Likely to get faster as the night gets
later, I would guess.

Thanks Sterling...so I probably don't have the HUGE one, since I'm on a
simple broad-band connection. The pic a have is, maybe, three times the
width of my 17" screen. Since this is probably a junior download, can
you
provide the link for the mega-big-one? Thanks!
