While—at least in the case of images uploaded to a ftp server via an Ethernet connection or a WT-6 or WT-5 wireless transmitter—the camera indicates upload status by the color of the transfer icon, transfer status is not displayed when pictures are viewed on a computer.
If On is selected for Network > Options > Send marking in the camera setup menu, the date and time of upload will be embedded in the copies on the memory card.
If pictures taken at the above settings are later copied to a computer, you can open them in the latest version of ViewNX-i or Capture NX-D and check whether they have been uploaded from the camera.
The date and time of upload are added to pictures after transfer and can not be viewed on the receiving device.
