But what about the examples in the article regarding a public or shared computer. I certainly don't want to install the iCloud plug-in attached to my Apple account on a school or friend's computer just to transfer a photo. This is designed to get photos from any iPhone to any Windows PC without having to worry about going through potentially private accounts like OneDrive, DropBox, or iCloud.Apple already has a perfectly good and free solution in My Photo Stream (not the premium iCloud Photo Library service). Just take a photo on your iPhone and it's there on your PC within a couple second. I believe you need to install iCloud plugin on your PC to get this to work on Windows. With a Mac, it's an automatic process if you use the same iCloud account on both devices.
The big limitation I see is a lot of systems utilize a different IP addressing scheme between Ethernet and Wi-Fi which would likely result in a failure to link up. Not a big issue when dealing with laptops, but in a school setting most computers are still hardwired.
Easiest solution is to hook the phone up using a USB cable, hit the button to allow the computer to access the phone, and browse to the photos folder. However, I also understand most people aren't carrying around a lightning cable with them. This wi-fi solution is better than nothing.
