How Can I change wallpaper from CLI?

[Gilles Caulier]

There a task assigned to a student this summer to open Plasma API for
wallpaper purpose. I mentored him to patch Plasma and write relevant
Kipi plugin for digiKam.

This code (this patch) for Plasma is not yet integrated to KDE core.
For me, it become urgent that KDE desktop provide this simple and
usefull feature...

For details look here :
