After having a WU account since 2011, and after years of deciding to put a webcam up, I have finally got the hardware.
I got a Raspberry Pi Zero Board with the Camera (V2), still awaiting on arrival of a 16GB Micro SD card to install Raspain onto it.
What I want to do is Upload it via FTP to WU and also have the software on the Pi save the images so I can transfer them onto a windows 10 PC, giving I will need the USB Adapter for it to put on a USB flash stick, so I can keep an archived data set of the most interesting weather days (Being in Adelaide Australia, interesting weather is a rarity in its own)
So what would be the best way/software to do this? I'm not the best at coding and whatnot as I confuse myself while doing it but managed to put CumulusMX on with ease.

The Pi cron utility is the simplest way to do this. This script that I am using should be close, you will have to change the 'wget' to use the Pi camera module instead of an IP camera. It is also overlaying weather data onto the image and trimmimg it to an size. The weather data is coming from a Meteobridge provided file. It saves the images in a 'day-of-year'-'image number' format and then each night I build a timelapse file.

Well I managed to write the script out (with the help of YouTube tutorails)
Just gotta figure out why it is coming up with the FTP: webcam.wunderground.com is coming up with Name or Service not known
-
'Cause WU webcams are no more.
-
The Pi cron utility is the simplest way to do this....
Brilliant, thank you.
-
'Cause WU webcams are no more.
Not true - WU has reversed on that plan and has now said that webcams will stay around.
This problem (Name or Service not known) is most likely a dns issue on the RPi. You should be able to type in :
$ host webcam.wunderground.com
And if your dns is working the response should be :
webcam.wunderground.com has address 54.148.11.142
webcam.wunderground.com has address 52.37.52.183
webcam.wunderground.com has address 52.36.136.128
If you do not get that answer, search the RPi forum in the 'troubleshooting' section for common solutions to this problem.
You can bypass this error by changing 'webcam.wunderground.com' to 54.148.11.142 - this might allow you to send photos to WU now, but it does not correct the problem.
That ip address is the webcam server that allows 10000 users, so most of the time it will accept your photo. The other 2 severs are only accepting 50 connections so most of the time you will not connect to them. But there is no guarantee that WU will use the photo. Right now I am sending photos every 15 minutes and about 90% are successfully transferred. But there are only about 5-10 per day that show up on the web page.

Ill give that a whirl and see how I go otherwise I will look into an alternative
If anything, I’ll set up my own webpage VIA Cumulus and send it to that site

only 1 of the 3 is correct, this is what I got:
webcam.wunderground.com has address 52.37.52.183
webcam.wunderground.com has address 52.34.136.128
webcam.wunderground.com has address 52.148.11.142
