Rotate wallpapers per batch

Question

We need a batch for changing the wallpapers at logon and after that change it every T minutes.

What I already found is reg add "HKCU\Control Panel\Desktop" /v Wallpaper /f /t REG_SZ /d path_of_image RUNDLL32.EXE user32.dll,UpdatePerUserSystemParameters

This works good for one particular image. But we have a couple of images to switch. Is there a possible way to set a folder per batch?

I have to second what Andriy M suggested in using task scheduler, as you mentioned you wanted to push it to every machine in your domain have you considered using a GPO to push that out?

The Microsoft walkthrough on using GPO to assign a scheduled task is here:

I would probably use two separate tasks for it, one triggered by logon and then one triggered on a set amount of time (i.e. once every 15 minutes).

I'm a huge fan of GPO as you can use it for everything from requiring password changes to blocking the ask toolbar from installing.
