Customizing the splash image in Bootloader

Customizing the splash image in Bootloader

The splash image is the image shown in the background when GRUB (the Grub Shell) is displaying the list of operating systems you can boot.
Normally, this is the corporate logo of your Linux distribution. But its very simple to customize it to an image of your choice.
All you need is the GIMP and gzip.
For this you have to follow the simple steps
firsty you need root access and follow the simple steps

1)Start the GIMP.

2)Click on File->New or type Ctrl+N

3)In the new image dialog, change Width to 640 pixels and Height to 480                  pixels. (The image should be of size 640x480 pixels.) Now click OK.

4)Create the image which you would like to be the splash image.

5)After you have finished creating the image,
    hit Alt+i or right click on the image and click on Image->Mode->Indexed...

6)In the Indexed Color Conversion dialog that appears,
    click on the radio button "Generate optimal Palette" and
     in "# of colors" enter 14. Click OK.(The image should be of only 14 colors)

7)Now right-click on the image and click on File->Save As...
     Save the file as  splash.xpm in a directory of your choice.

8)Now open a terminal window and navigate to the directory where you have
     saved splash.xpm

9)Now key in gzip splash.xpm

10)You will find that a file named splash.xpm.gz is created in the directory
     where splash.xpm used to exist.

11)Copy this splash.xpm.gz to the /boot/grub directory.
     You may want to back up the pre-existing splash.xpm.gz file in
      the /boot/grub directory first.

That's it! When you reboot, you will find your image in the background, with the menu of operating systems etc. in the foreground.
