Weather Underground Image FTP?

I have seen a few people that use the Reolink cameras to upload an image to Weather Underground, however looking on these forums it appears that the cameras themselves do not support this; without sending video also. How are others doing it today until Reolink is able to address it in their firmware? Are you accessing the camera via the URL and scripting this to be FTPed up to Weather Underground? I just bought an extra camera for this purpose as I thought it could do images only, but it seems I did not do my research before the purchase.

Any pointers, scripts, or other details others can share that would get me started down the right path?

Thanks!

I forgot to add that this camera is directly attached also to a 16-port NVR so it is not an IP that I can address on my local network via a browser. I need to send a command to the NVR (with the correct channel) also to retrieve the jpeg.
