My wife just upgraded from an iPhone 5 on iOS 7 to an iPhone 6 on iOS 8. She restored from backup in iTunes and is pleased that all of her apps and app data were restored with no issue. Due to space constraints, though, she doesn't want her old iPhone photos on her new iPhone. She's already imported them into iPhoto on her Mac and we have them saved. However when we go into her iTunes, connect her new iPhone, and go to the Photos section, "Sync photos from iPhoto" is unchecked. How can we safely remove the photos from her iPhone without affecting the iPhone 5 photos from her old phone that we imported into iPhoto on her Mac? Thanks!
