Well I tried the mkdir Public/myFakeNAs and it worked this time! I have
no idea as to why it didn't before.

Presently the NASname = os.path.join("/mnt/CCTV/PiZero" , fname)

After running the script and a picture shows up on the monitor, it does
not get saved to the /CCTV/PiZero directory, nor on my NAS box.

I realise there is something else I have to do but not sure what.

I think this was answered before, but as there are many posts on this
thread, I can't find it just now.

Thanks
