Thanks for responding, HipMaestro.
From the top, then. All file names match the required sizes (and all images *are* the required sizes - checked and rechecked). None of the images appear corrupted outside of NWN. All image names are original - necessary for me to keep track of what I was doing - and don't conflict with the vanilla portraits. Recreating the images will be my next step.
I was familiar with the information in your link, but not with the Convertportrait console command. Unfortunately, it doesn't seem to work.
'> Another mystery, but given the level of control I sacrifice by using it, I think it would be a last resort measure at best anyway.
Looking back, I notice I forgot to mention that all the images giving me trouble are from the same set - a woman in a black gown, for instance, appears blank in all five image sizes, as far as I can make out. This implies an issue with the original image. Could it be compressed? I was given to understand I wouldn't be able to edit a compressed image at all.
That doesn't seem to explain the upside-down images, though. As you say, peculiar.
