I use an applet called Loginox which replaces the file
System/Library/CoreServices/DefaultDesktop with whatever image you
wish. At the same time the original DefaultDesktop file is saved
somewhere and Loginox provides an option to restore it as the active
login screen.

Does it "keep a COPY" ? or does it just move the directory entry to
another directory, i.e., move the original? Moving the original will
not break any aliases that point to it. This may even include aliases
encoded in base64 and embedded in plists.

I wouldn't be surprised were someone to tell me that an application's
resource fork can contain aliases to files the app uses or that a file's
resource fork can contain an alias to the app that opens it.

Loginox changes the .jpg file
System/Library/CoreServices/DefaultDesktop to the image file you choose
(I don't know if Loginox accepts other than .jpg files) and apparently
saves the file it replaces somewhere. At least if I traverse to
System/Library/CoreServices the file DefaultDesktop.jpg will now
contain the image I chose via Loginox. Loginox has the option to
restore the DefaultDesktop file to whatever it contained prior to the
use of Loginox, and in my case that image is the "Aurora" one. Where it
saves that restoration file I do not know.

in my scenario, the important thing is _how_ it puts it there.

Perhaps that's at the root of your problem.
