Networking :: How To Remotely Update Lockscreen Wallpaper Slideshow

At my company, we have about 20 laptops that run Windows 10 and are connected on a local network. All are domain-joined and connected through AD. One of my favorite features of Windows 10 is the lockscreen slideshow. This is what you initially see when you boot your PC, and is displayed with the time, date, and other icons. By selecting multiple photos, Windows will create a nice slideshow and display them on the lockscreen. I have about 30 photos in a folder that I've used to create a slideshow.

Here is what I'm trying to achieve. I'd like to set every machine on the network to have a lockscreen slideshow using those photos. I could do it manually, but that poses two problems. One, it's very time consuming, and needs to be done for new PC's as well. Secondly, I'd like to be able to add new photos to the 30 I have, and have them add to everyone's lockscreen slideshows. If I manually added them, I'd have to go to each machine to update with the new photos.

One solution I was thinking of was to point the directory that Windows gets the slideshows from to a network share that contains the images. But I worry about what will happen when a user is away from the office and doesn't have network connectivity to that drive.

The best solution I can think is to have a script that will copy the lock screen photos from a network shared folder to a local folder on C when connected to the network. It would need to only add photos that aren't added already to avoid duplicates. That way, the files are locally accessed, but can be updated remotely, and there aren't any issues with leaving the network. The script could be distributed through group policy.
