Version: (using KDE 4.3.0) OS: Linux Installed from: Ubuntu Packages kcm_kdm has a tab "Background" where you can select a picture and a position. Unfortunately, the preview on the right hand side does not update when changing the picture or the position property. One has to e.g. minimize and restore the window to enforce a repaint of the preview area. The preview picture should be repainted everytime when the picture or position property changes.
