That does seem to work for my purpose. I didn't read your post carefully enough and attached them individually. Even if I had used the bulk actions, it would have been significantly more effort than it used to be. [Without bulk actions, it was another extra dozen steps.]
If upload to a post didn't do the auto-rotate, or at least gave the option to edit rotation after upload, then this would not be so frustrating.
BTW, I uploaded the same images to PicasaWeb, and it did the same incorrect auto-rotate for the same images. However, it had icons immediately available to correct the rotations.
