Watch folder for Photos When I'm on my iPhone, pictures downloaded from the Internet are automatically uploaded to my iCloud Photo Library.  

I want the same thing to happen for pictures downloaded from the Internet when I'm on my Mac. Let's say I want to upload to the Icloud Photo Library every new image in the folder Downloads.

Is there a way to do it seamlessly ?
Add Photos actions to Automator using https://photosautomation.com/ 
Construct the following Folder Action in Automator



I'm still not 100% satisfied, since folder actions are not super robust so I welcome other answers!
