I am a user that is new to iPhoto and the world of Mac. I’m running iPhoto 9.5.3 on a MacBook Pro running OSX 10.9.5. I’ve had to manually sort old vacation pictures that I brought into iPhoto and placed in an album. All went well and looked good until I ran slideshow. That runs backwards. Looks nice but starts with the last slide and runs toward the first. Any idea on what I broke and how to fix is appreciated. It seems to be just the one album.
