Today I upgraded from an iPhone 5s to an iPhone 6s via the Verizon store. The clerk told me everything would be transferred between phones automatically. After getting home I discovered my photos on the Camera Roll were missing. The Camera Roll folder and all album folders are there. They contain blank photos. When I click on a photo it displays a blank frame, but the correct photo date.
All the iPhone photos are on my iMac. So then I wonder if there's any easy way I can transfer the photos from the iMac to the iPhone. The Camera Roll contains 1,667 photos so I am really hoping i don't have to do this on a photo-by-photo basis. Also, a photo may be in more than one album based on who was in the photo. Also, the iPhone photos were not stored in iCloud. Help!
