Unwanted image rotation

Just noticed something odd:
If I use a PicturePicker and choose a picture (the pink flowers) from the sample images in the iOS simulator
-then apply it to an ImageView

It appears OK

If I save the image as a PNG file, then open it later and apply it to the same ImageView, it is upside down.
Somewhere along the way , I assume the EXIF information is being lost.
Is that expected when saving a photo in Xojo iOS?
