I've never used any splash/image on grub (or worry much for the OS 
splash, come to think of it), but I think what happens is that your 
screen is not set to what the grub vbe can handle, meaning the "gfxmode" 

To check what grub can handle (which is different from your OS screen 
resolution), at grub prompt (grub>), the command "vbeinfo" should list 
all available resolutions for grub and you must use only what is listed 
there (it's a long list) for your splash image.

But since you said it returns error message, suggest you try "insmod 
vbe" before doing this.

grub> insmod vbe
grub> pager=1      (#long list: so you can scroll)
grub> vbeinfo

Then select one resolution that correspond to your chosen image at the 
gfxmode part. Don't forget to update-grub.

Good luck - Goh Lip
