Picture Transfer Protocol (PTP) is a widely supported protocol developed by the International Imaging Industry Association to allow the transfer of images from digital cameras to computers and other peripheral devices without the need of additional device drivers. The protocol has been standardised as ISO 15740.
It is further standardized for USB by the USB Implementers Forum as the still image capture device class. USB is the default network transport media for PTP devices. USB PTP is a common alternative to USB MSC, as a digital camera connection protocol. Some cameras support both modes.

“... everybody who is human has something to express. Try not expressing yourself for twenty-four hours and see what happens. You will nearly burst. You will want to write a long letter or draw a picture or sing, or make a dress or a garden.”
—Brenda Ueland (1891–1985)
“If it had not been for storytelling, the black family would not have survived. It was the responsibility of the Uncle Remus types to transfer philosophies, attitudes, values, and advice, by way of storytelling using creatures in the woods as symbols.”
—Jackie Torrence (b. 1944)
