You can transfer pictures from your iPhone to a flash drive, but you’ll need to purchase a special one that comes equipped with a lightning port. For better or worse, Apple still hasn’t switched their iPhones over to USB-C, so you’ll need to buy a special iPhone flash drive (see above) that allows you to connect to your phone with one end and a computer with the other. This way, you can pull photos and other data off of your iPhone using the lightning port, and transfer it to your computer using a standard USB Type-A or Type-C port.
