[xubuntu-users] Can not change background

[Tim]

Hi

I have a new 14.04 install and I am having a problem with the desktop 
wallpaper (background). I have a folder in my home folder where I store 
my images for my wallpaper. If I right any where on the desktop (or go 
start > settings > desktop) I have the option to choose the folder I 
would like to use for Wallpaper, I choose the folder in my home folder 
and select change the background every 9 minutes and select close (there 
is no save option). If I open the desktop settings again the folder for 
the wallpapers will have reverted back to/usr/share/backdrops The 
backdrop folder contains 54 images which change after every 9 minutes. I 
guess I could simply move my images into the /usr/share/backdrop folder 
but that is not the point there is an option to use a folder of my choosing.

Anybody know how to get it to accept my folder??
