I ran into a similar problem when I upgraded my phone to a Samsung 5 (battery) and Windows 10. I connect my phone to the computer via a USB cable. There is a pulldown menu at the top of the phone and it will display that I am connected to my network and that is charging via a USB cable. Select USB cable charging option and there will be several options, Charging, File Transfer, Photo Transfer, Software Installation, Midi and Media device. Select Photo Transfer and it should allow you to go to your file explorer and it will display your phone (Mine is SAMSUNG SM 900V)It will display PHONE and CARD. Check both and go the DCIM folder. Depending where you save your pictures, it should bring up all your photos on your phone in one of those folders. There may be additional folders in the DCIM folder and go to the one called CAMERA. You should be able to do a copy/paste on the ones you want and transfer to your computer. Hope this helps.
