Everybody(using a picture as wallpaper) has experinced it once. You found an awesome new Wallpaper, but in the settings you can't find it properly (with all the info). Or you did an wallpaper and simply uploaded it. This problem is now over.
Wallpaper-tool is here.
As you can see it's a really simple app only a few fields and so.
After you have set all up you press create and you are done. For artists or people who want to upload that wallpaper. The folder you want is in ~/.kde/wallpaper/
You can get it via git clone git://anongit.kde.org/scratch/kolberg/wallpaper-tool
I hope you can enjoy it
