Wallpaper Scripts

Powershell Script to generate wallpapers for your network.

Based on @DJ-1701 s original scripts from https://github.com/DJ-1701/GenerateWallpaper.

Usage

1. Download and save a copy of this repository or just wallpaper.ps1 to somewhere on your network. e.g. NETLOGON.
2. Create an ini file for your wallpaper. See INI Files below.
3. (Optional) Use GPP Files to deploy the script, ini files and wallpaper to the local machine e.g. C:\Wallpaper\wallpaper.ps1
4. Configure a GPO to run the script with ini at the right time. E.g. a statup script of C:\Wallpaper\wallpaper.ps1 -ini C:\Wallpaper\boot.ini and a logon script of C:\Wallpaper\wallpaper.ps1 -ini C:\Wallpaper\logon.ini
5. (Optional) If generating a lock screen use a GPO to force a specific lock screen.

INI Files

To configure the ouputted wallpaper you supply an ini file. The INI File is split into a few sections, files, header and footer.

There are 2 sample files of boot.ini and logon.ini which demo how to create a per-computer lock screen and a per-user wallpaper.
