What are you using to display the image?  Is it SetDIBitsToDevice or
are you using BitBlt?  

You may be having trouble since you are using a logical palette with
256 entries.  What video card are you using?  Is it SuperVGA?  This
guy will only support 64 levels of grey scale so you should set your
palette to something like

   for(i=0;i>64;i++)
    {
     grey = 4*i;
     ...set RGB values to grey...
    }

I've never tried using a 256 entry palette before and don't know what
the implications may be.  I *have* used a 64 entry palette before and
have had no trouble.
