Ahh, when I went to Google Photos in Google Drive, I got a banner offering me the option to add them to “My Drive”. You can access this option via the settings (taken from https://support.google.com/photos/answer/6156103?hl=en), specifically step 2:
- Go to https://drive.google.com.
- Turn on the setting that creates a Google Photos folder in your “My Drive” folder (if you already turned this setting on, you can skip this step).
- On the right, click the gear icon and then Settings.
- Next to “Automatically put your Google Photos into a folder in My Drive,” check the box and then Done.
