hi,guys
I have got Fedora 7 installed on my PC and recently I wished to change my grub image so I went abt changing it as follows:
I had a JPG image "flower.jpg" (size 1024x786) which I converted to .xpm form using the following command:

#convert -depth 8 -colors 14 -resize 640x480 /root/desktop/flower.jpg
/root/desktop/flower.xpm

then i compressed it as "flower.xpm.gz" and copied it to "/boot/grub" folder.

finally I made changes in the grub.conf file in /boot/grub ,in the
line "splashimage=.........." where I changed the filename from splash.xpm.gz to flower.xpm.gz

I rebooted my system but the image that appeared on my grub was highly distorted and it did not even fit the screen when I had resized it to 640x480 .

can anybody tell me what could be the problem?????????

Fourteen isn't very many colors.
Try this to verify the image looks good:

gzip -cd /boot/grub/flower.xpm.gz | display
