Confirmed(!) THIS PNG image looks correct to me--both the small preview as
well as the larger hi-rez version, when clicking on the preview.

This is indeed strange-- but at least I now have a clue as to what might be
going on, within Photoshop (and how it treats POV-Ray-generated PNG
renders--possibly changing their gamma when I certainly wasn't expecting that.)
I need to test this further.

However...this does NOT explain the difference in appearance here of my
originally posted PNG's-- the previews vs. the hi-rez versions. The only
possible explanation I can come up with is that the newsgroup 'previews' are at
one gamma setting, while the hi-rez versions are shown with a different setting.
Sounds a bit crazy, I know...
