At work I like to get the wallpaper from worldstart.com. Is it possible to use this wallpaper for Windows in KDE and GNOME?
...Yes. Just download it at the proper resolution for your screen. In KDE you can install the wallpaper (unfortunately on all desktops) simply by dragging it to the desktop and choosing "use as wallpaper" (WTTE) in the context menu.
