My son has set up a Raspberry Pi in the home to display images. He enabled FTP and told me to connect via WinSCP. I have done this, and I see all the folders on the Raspberry Pi. However, I cannot upload images or do anymodifications on the raspberry pi due to a permissions problem.
Any ideas what could be the cause of this?
I am logging in with his username and password, which has full rights to the Pi.
