JPEG format may contain a thumbnail that is just another image, that should be generated out of the contained image, but in fact it can be something completely different. Maybe they have edited the main images, but somehow forgot to update the thumbnails in them (rather odd, because every image editor should do it automatically). The thumbnails in JPEG can be of various sizes, even quite big, and there are programs that can extract them to standalone images. Maybe you could try it and see if they contain anything interesting.
