Scrapbook pictures not oriented correctly

Half of my pictures in the Scrapbook are showing up not oriented correctly (sideways vs. vertical). I have changed the orientation on my computer, buts that does not work. How do I correct this situation? I see other topics on this but no answer.

You might need to change the EXIF Orientation Flag in the image’s properties.

Thanks, I’ll have to figure out how to do that. I thought it would work by changing the orientation in Windows Explorer but it didn’t.
