get all photos off iphone to pc
I would like to get all of the photos off of my iPhone 4s onto my pc. My pc (running Windows 8) does not recognize the older photos, and is skipping some of the newer ones. It's only recognizing the last 70 photos, when I have 650 on my camera roll. How do I get them all onto my pc? I've researched and researched and cannot find the answer.
iPhone 4S, iOS 8.4.1
