iPhone Where to download wallpapers to?

[Super Spartan]

I Googled some iPhone 11 Pro Wallpapers but I don't know how do you guys go about saving them? I wanna keep them somewhere separate and not have them appear in my Photos app. Is there a way to do that or how do you guys get new wallpapers?

Store them in Google Photos. Then, have the same said app on your iOS device.
Alternatively, save them in a Cloud storage, like Box or Dropbox, or even OneDrive...
