It's in the file /etc/lightdm/unity-greeter.conf
. Open it with gksu gedit /etc/lightdm/unity-greeter.conf
from a terminal or run dialogue. Set background=
to whatever file you would like.
However make sure that file is accessible to all. It can not be in an encrypted home folder or such. The problem you have is most likely due to unity-greeter
for some reason can't access the file you chose.
An easy down and dirty way is to simply replace /usr/share/backgrounds/warty-final-ubuntu.png
with the image of your choice
sudo mv /usr/share/backgrounds/warty-final-ubuntu.png /usr/share/backgrounds/warty-final-ubuntu.png.bak
sudo mv new.img /usr/share/backgrounds/warty-final-ubuntu.png
sudo chmod 644 /usr/share/backgrounds/warty-final-ubuntu.png
Ideally it would be a .png, but other images work as well.
The only disadvantage (IMO) of this method is that /usr/share/backgrounds/warty-final-ubuntu.png
may get updated with system upgrades.
