Its not that the quality is low - the pictures are either littered with 
brightly colored squares or discolored areas, and some are completely 
unrecognizable.  The weird part is that they're only hosed in PDF - 
they look fine on the screen.

I went back into the document and deleted out all the hosed images and 
re-pasted the original back in, and that fixed it, though quite a pain 
in the rear. My guess is that PowerPoint shows some kind of rendered 
"thumbnail" on the screen that it generates from the original image, 
but it keeps the original asset tucked away to use for printing - and 
its that original asset that got corrupted somehow.

If its a known bug, I'd sure want to avoid doing whatever causes it.
