Lol, you can't have both. You are not logged in at the greeter screen so you cannot have unity-greeter read from a directory that is only readable to your user account. The two things are mutually exclusive.
If you dont want your directory readable by other users/when your not logged in then you need to store your background images outside of your home directory.
Just to put the last nail in this coffin any hack to allow unity-greeter to access a directory it doesn't have access to would mean a huge security flaw in linux. As effectively your saying anyone should be able to access files they don't have permissions to.
