Could it update the lock screen picture as well? I find that a lot more interesting than the desktop which I barely ever see.

There's another project that does exactly that, City Art Search: https://www.microsoft.com/en-us/store/p/city-art-search/9wzd...

Please also note that you might be better served by a new "Preview" version here: https://www.microsoft.com/en-us/store/p/cas-preview/9nblggh4...

Don't know why they still keep it in preview.

Wow that's the first app from the Windows store that I actually wanted to install.

It's very nice on Windows tablets and phones (a vanishing species, unfortunately).

The author has posted about it on Reddit: https://www.reddit.com/r/windowsphone/comments/5yjdpp/city_a...

I presume you mean on Windows. Unfortunately this is pretty difficult. I'd like to make it happen so I'll look into it again at some point.

I use a screensaver on my Mac, and it seems like it refuses to recognise the image in ~/Library/Application Support/Artpip/images as an inmate without the .jpg extension. Is there any chance of you changing the images to use a .jpg extension, so I can set my screensaver to use your folder automatically.

Interesting. Yeah, I can do that.

But it's not an UWP.

Yep. You can now call these APIs from the desktop, AFAIK.

There may be a little more to it, but sadly after setting it up for a couple hours, it seems the TrySetLockScreenImageAsync method always returns failure from a non-UWP app :(

If anyone else wants to tinker with it https://gist.github.com/Connicpu/8b092b2c0ad539573b893dbca54...

Sorry. Seems it's limited in what paths pictures can be loaded from. Bloody Microsoft.

from what I recall you are able to set it from the registry.

create this key with a string value called 'LockScreenImage', this string should point directly to an image, i.e: C:\.... HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Personalization

throwaway because of not wanting to get arrested for hacking the registry
