On Samsung you can Backup the phone with the Kies or Smart Switch software - depending on model of phone.
At least some of the photos (normal Camera ones) are put in the folder named like
C: \Users\Tim\Documents\samsung\SmartSwitch\backup\SM-G920F\SM-G920F_your-phone-number\SM-G920F_other-magic-number\Photo\DCIM\Camera
SM-G920F is the model of phone in THIS case.
