I'm afraid I still don't quite understand the question. Are you talking about the new Google Photos app on your phone, or the new Google Photos on your computer? When you say you want Photos to pick up all of your pics, do you mean you want the Photos app on the phone to display all photos that are saved locally on Internal Storage as well as in your Google+ Photos on the web? Or are you trying to use Google Photos on your computer browser to upload all photos that are locally stored on your computer?
