What is CFNetworkDownload and why is it changing my Wallpapers?

Thanks. Unsplash was the problem. Removed it from login. Problem solved.

My wallpapers suddenly started changing and even if I changed them back, they changed again and always to a CFNetworkDownload_KhbSZ0 (though the bit after "Download_" changes, even though the picture it changes to always changes to the same one"). I discovered that the "CFNetwork" is something to do with Mac OS.

What is CFNetworkDownload?

Why/how is it changing my wallpapers?

How do I stop it?

Can I get rid of it?

I have no idea how to stop this intrusive behaviour. Please advise.

Thank you.

I am well used to changing wallpapers and have been doing it since Snow Leopard (OSX 10.6). This is something that only started happening recently. I assumed that it had something to do with a MacOS update on my iMac Retina 5K, 27-inch, 2019. My computer has never done this before.

Any ideas on how I can remedy the situation. FYI I am not a "computer person" (I am just a bit unnerved by my computer acting apparently randomly after years of "normal" behaviour.)
