Login screen file location 10.7.4

It looks like the most recent revison to OS X, that being 10.7.4 moved, or otherwise changed the way the system displays the background image for the login screen. I use a custom image file for mine, and now that same file does not display in 10.7.4

The file (my coustom image) is still there, but it looks like OS X does not use that file anymore.

This is the file name:

/System/Library/Frameworks/AppKit.framework/Versions/C/Resource/

NSTexturedFullScreenBackgroundColor.png

Does anyone know how to customize the login screen background in the new build?
