I was having problems with sideway photos too, and here is what is working for me. It may be more trouble than it's worth for you, but here's what I have been doing.
I take a photo of an old photo on my iphone, then I use the App on my phone, called Photo Editor (it's free). I make sure the image is pointing the right way, then I put a Vignette on the photo, and save it. (A Vignette is a dark or light circle or oval around the subject in the photograph.)
Then I use my phone to download the edited photo to whatever profile I'm putting it on.
If you're using a computer with a camera card, then I'm sure that there are photo editors you could use on that too, I'm just not familiar with them.
I really hope this helps!
