I started up my computer, and my wallpaper/background was gone: It shows only a white background with the desktop icons and the icon bar.

The wallpaper I have chosen from my pictures (beach/sand), is still selected inside of KDE 3.5 / KMenu, but the previewing picture is showing a blue screen.

The previewing screen used to show the wallpaper that I had selected. Then I was able to press "Apply", and all whent fine, before.

And what I can see, is only a white desktop background.

Please help.

àEdit:
It is working again:
I downloaded the picture again.
