The only way I know how:
+Add > Photoset > Select Photoset Name > Choose Files >
iPhone gives me 3 options
Photo Library seems to be the choice for photos taken with the phone.
- tap Photo Library
- select a category
- tap a few thumbnails & a blue check mark indicates what is selected
- tap Done in the upper right on the iPhone and they load
Perhaps someone knows an easier way or about Google photos
Hike Arizona it ROCKS!
