For avoidance of doubt, 192.168.1.x in the example means a network that user set up, using a router chosen by user, running OS that user compiled from source. It does not mean a network open to the public, or someone else's network. Apps like "Airdrop" and other "secure" file transfer apps seem to encourage use on other people's networks, and many of them require an internet connection, and often use third party servers by default. In the example, neither phone nor laptop has an internet connection, only a connection to the router that user controls. The router does not have an internet connection either. (Compare using Wi-Fi Direct via a closed source app from Apple.)

Best solution: Do not take photos with a "phone". Use a "camera".
