The photos were taken on two different types of iPhones.
The photo above, one of those cited as a problem, was taken with an iPhone 4. I have tried rotating it, then saving it under a different name than on the file sent to me. While I don’t expect that to work, who knows?
Does it look right on your browser and phone/computer? And what are you using to view it?
