I created these images because I was unhappy with the GTK Login Splashes that come with the Mac4Lin Transformation Pack (http://sourceforge.net/projects/mac4lin). Since making these I have also made a GDM login screen and I'm working on a Usplash that I'll see about posting once I have it finished.
You'll need a program that lets you change the session splash to use this file. On Ubuntu syetms you can use Ubuntu Tweask (http://ubuntu-tweak.com) to make the change.
