Comment 7 for bug 926726

I have now tried to copy an image to the /usr/share/backgrounds folder and set the same owner and permissions and then set it as background. It does not show it as my background in lightdm. When I choose the picture I have to choose it under the "Pictures Folder" in the drop down list. It does not exists under"Wallpapers" like all the other pictures in the /usr/share/backgrounds folder.

So the bug seems to be that lightdm will only display backgrounds when it's part of the Wallpapers list not necessarily in the right folder on the PC.
