Thanks, Straybow, for the work-around suggestion.  It works well enough; though, one has to be very determined to get satisfaction.
I had bookmarked those pages and refer to them on occassion, most recently about two weeks ago.  At that time everything loaded w/out difficulty.  I was surprised and perturbed today when they broke.
BTW, when I opened the thread with Netscape 7 (rather than 4.79) there was no problem with the image attachments.  May have to dump the earlier version if Poly no longer works with it.
I noticed that these pages are now referenced (and I think, memorialized) in a "hidden special" thread on the Strat forum.  "And that's a good thing."
