[SDL] Image of 8bpp in a surface of 8bpp

[Fausto Carvalho Marques SIlva]

I'm having problem with an image loaded with SDL_image and displayed in 
a 640x480x8 screen.
This image is a jpg and when displayed in 640x480x8 it gets distorced, 
but with 640x480x16 it
does not get distorced. But in my mind if the image is 8bpp and is going 
to be displayed in a
screen of 8bpp that no big deal.Anyone can help me??
Thanks...
