Add splash image to GRUB

I wanted to add something to the default GRUB screen that greets you as you start Linux more nicely than monochrome text.
I did this using the splashscreen feature of GRUB version 1, the boot loader that I had installed.
I used Krita for some of the image manipulation, but GIMP is also a good app. On Debian, you can get GIMP as root with

Splash images in GRUB have to be in .xpm or "X PixMap" format and they have to be 640x480 in size, and 14 colours.
I found a nice image of tux on the internet and converted it to the right format.
For interest, images can be .xpm or .xpm.gz (a gzipped image) which are created using

Images are completely uncompressed and compressing using gzip does significantly reduce their size, however it's not really necessary given that they are only ~300KB anyway.

I placed the image in /boot/grub

To make the image appear during boot, I added the line to /boot/grub/menu.lst
This file may be called something different depending on your distro.

(hd0,0) may be different depending on the location of where Linux is installed for you. There should be a section in this file that looks something like this:

In this case (hd0,1) should be used. This is probably the easiest way of figuring out your drive's GRUB designation.

I could not get really good results with Krita, but I was able to find a nice Debian package (there may be a similar package for other distros) with pre-made images

These images are placed in /boot/grub/splashimages/ and can be accessed using a line such as
