How to copy a photo from Windows to iOS without needing Internet servers

Apple products don't work in the real world so something as trivial as
copying a photo from Windows to iOS is almost impossible without the net.

In a Windows/Android thread, we've been discussing how to use screenshots
to get past Android security, when Steve Sharf noted that iOS lacks
Android's security so we can successfully screenshot iOS on Windows PCs.

  "Ironically, iOS doesn't have the capability for apps to restrict
   screenshots. I've used an iPhone, on at least two occasions, to do a
   screenshot of a virtual ID card that I wanted to add to my Google
   Wallet. Transferred the image from the iPhone to my Android phone."

So the plan is to install these apps on iOS & Android to do cartooning.

iOS "Photo Lab"

Android "Photo Lab"

The main problem now is how to perform the trivial task of copying
a photo from the Windows PC to the iOS device without using Apple's
iTunes abomination bloatware (& insecureware), or Internet servers.

Has anyone on this newsgroup ever copied a photo from Windows to iOS
without having to create an account on someone's server on the net?
