Relationship of iCloud Photos via browser vs. iCloud Photos app on PC?
I have two ways of accessing iCloud Photos on my PC (listed below). What is their relationship?
Access via iCloud.com using a browser -
I can specify the Apple ID I want to use and it is quite intuitive.
Access via the iCloud Photos app on my PC -
+ when I start this app it takes me to the iCloud Photos directory on my PC.
+ there are three directories/albums: upload, download and shared.
+ how are the three directories/albums related to what I can access via iCloud.com???
+ is there documentation on how these two access methods work together?
+ when using this access method the Apple ID is fixed. How is it fixed in the first place and how can I change it?
