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.

I see exactly what you are saying, it would be a security flaw to allow unity-greeter to see your home folder with those permission.

But surely it's very reasonable to have your home folder only viewable by yourself, i'm sure lots of people dont't want all their files visible to other users of their computer.
What i suggest is have Ubuntu automaticly copy your desktop background to a common folder, so unity-greeter can use that folder.
