'Get New Wallpapers' saves images to wrong location

In Kubuntu with KDE 4 if I use the 'Get New Wallpapers' option to download additional images they are saved in a completely different location from the default preinstalled wallpapers... ~/.kde4/share/wallpapers/ instead of root/usr/share/wallpapers

Not only is root/usr/share/wallpapers the location of preinstalled wallpapers, but it is also the default folder for Slideshows. This means if a user wants to select 'slideshow' as his desktop background, the default folder contains none of the additional 'new wallpapers', even though she has just installed several she would expect to be listed there.

Unless she happens to know the obscure hidden folder the wallpapers are downloaded to she can't select them for the slideshow, or access the files to do anything else with them (say to edit them with GIMP)

Theres two problems at the heart of this:

1. Preinstalled wallpapers and the default location for slideshow wallpapers do not match the location additional wallpapers are downloaded to.
2. That second wallpaper folder located in .kde4 is in a really obscure, literally hidden place. If you are going to ignore the original wallpaper folder at least make it somewhere obvious to get to like home/pictures/wallpapers or something.

Hope this makes sense.

I just wasted 90 minutes of my life trying to find out where my newly downloaded wallpapers had been saved to. That is EPIC FAIL.
