1.	First, you need an image with a resolution of 640x480, because grub only supports this resolution.
2.	Convert the image format to XPM because grub only supports images in this format.
3.	In addition, the image color depth of the XPM must be 14, and the above requirements can be completed with a command: # Convert-resize 640x480-colors 14 wallpaper.png splash. XPM The example command is to convert wallpaper.png to a required image splash. XPM.
4.	We can check whether the image meets the requirements of grub by running the following command: # More splash. XPM If this information can be found in the file header, it indicates that the image can be properly displayed by GRUB: /* XPM */ Static char * 10 [] = { /* Columns rows colors chars-per-pixel */ "640 480 14 1 ",
5.	Open the file:/boot/GRUB/grub. conf Find one of the rows: splashimage = (hd0, 2)/boot/GRUB/splash.xpm.gz (Depending on the release version, the path and file name may be different and you need to modify it yourself .) /Boot/GRUB/splash.xpm.gz is the final image to be displayed. Follow the instructions below to compress the image: # Gzip-9 splash. XPM
6.	The last step is splash.xpm.gz. Put it in the/boot/GRUB/path, replace the original image, and restart it to check your new image.
