you can actually do this:

inimage = Image.open('palette.bmp')
outimage = Image.open('convert.bmp')

outim = outimage.convert('P')
outim.palette = inimage.palette

outim.save('converted.bmp')


the only problam with this is that it doesn't do it very well. I decided
to read every pixel in the file to convert, and used my own algorithm to
convert the colors. 

I'll let you know how i get on :-)
