The 'take picture' command requests the drone to take a JPEG snapshot.
The process takes a little while to complete and during this period the video feed may freeze.
Sometimes [when?] the drone does not honour the request.
Once the picture has been taken the drone responds with a File Size
message which must be acknowledged. Then the picture is sent chunked into File Data
messages which must be reassembled to save the picture locally.
