Copy random image and use as Teams background

random-teams-bg.ps1

<#
   This script will pick a random jpeg from '$HOME\Pictures\teams-bg\' and copy it to the 
   Teams background image folder.

   To make it work, save this script somewhere and then rename *any* jpeg-image to 'stdbg.jpg' and
   use it as a custom background in teams. This file will be overwritten with the ranom background 
   image everytime the script executes.

   Then create a new scheduled task to execute 'C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe' with
   the argument:
    -command "PATH-TO-YOUR-SCRIPT\random-copy.ps1"
