Can't save changes to edited photo in windows photo gallery?

I'm downloading photos (sent from my iPhone to my email) to put on craigslist. My first few worked fine, but I just download another one and when I turned it clockwise and saved it said that the changes to the file could not be saved. I already tried looking at the properties to see if it was "read only" and it wasn't. I tried changing it on my phone and sending another copy to see if it showed up in the right direction, and that didn't help either… Anyone know how to fix this problem so I can change the photo from landscape to portrait?
