@Thomas: That folder (/usr/share/backgrounds) is owned by 'root'. To
copy files into that folder, you can do as compdoc has recommended,
and/or you can use the 'cp' command from the terminal. Open the terminal:

$ gksu nautilus

That will open Nautilus in root mode.
Warning: Be *very* careful doing this as you can delete/move/edit
critical system files here. Always exit from this mode after you've
accomplished what you need.
Now go to where your pictures are that you wish to copy, select them,
and then copy them to /usr/share/backgrounds the same way that you copy
any other file in Nautilus.

$ sudo cp <path-to-your-pictures>/<your-picture>
/usr/share/backrounds/<your-picture>

See:
https://help.ubuntu.com/community/UsingTheTerminal
<https://help.ubuntu.com/community/UsingTheTerminal#File_.26_Directory_Commands>
[5. cp]

This is considerably safer than using 'gksu nautilus'.
