Never mind.
Next time I post something like that and fail to check my own browser's image permissions... ("allow images from the originating server only"...) - which I had set that way, and recently...
Logging off for a bit to do some things. Meep!
Edit: stash images, not blog images, but I was having a problem here with all images which weren't Cherrytap-hosted- which eventually clued me off as to what the problem was.
Eventually.
It took awhile.
