Maybe what you're looking for:
https://help.ubuntu.com/community/Grub2#GRUB_2_Splash_Images
That link was for Grub splashes. Xsplash was the predessor to plymouth and plymouth replaced it in 10.04. The plymouth theme includes the default logo (ubuntu-logo and the five white/red dots), and the logon screen... also affected is the background color and any text...editing the theme profile file, you can change pointers to where images are located and to the theme script file to use....and in that theme script file you can either change everything or mess everything up.
For example the default ubuntu-logo.script is going to look to most as an overwhelmimg managery...

But if you copy the whole subdirectory /lib/plymouth/themes/ubuntu-logo/ to /lib/plymouth/themes/my_custom/ to make a duplicate that you can customise. > Copy in your image file > rename ubuntu-logo.script to my-theme.script > open that file > search for the string
logo_filename = "ubuntu_logo.png";
And change it to the name of your image. % lines above that isthe filename for a 16bit version of your splash image. Change that filename to your 16bit picture file. .. save and exit. > rename the ubutu-logo.plymouth file to my-theme.plymouth > Open that file and set the pointers of the image directory to this new /lib/plymouth/themes/my-theme/ directory. Set the script pointer to the /lib/plymouth/themes/my_custom/my-theme.script file. > Save and exit.
Then drop back down to the theme subdirectory > copy the /lib/plymouth/themes/my_cutom/my-theme.plymouth file over/replacing the default-plymouth file... Then update the boot image to include your changes.
sudo update-initramfs -u
Thats the basic instructions for how I do it. There are some other tools that save some work on picking colors, placing objects on the 2 screen panels and switching between different themes... But if I want to add my "own image"... (Usually someone's company logo, a satirical distro logo or a personal pic)
EDIT-- There is a package that automates all that in a GUI based tool called "Plymouth Manager." I haven't used it... It's not in the Ubuntu repo's. It is a project at launchpad and is available here:
