gtk.gdk.Pixbuf does have a save method

http://www.gnome.org/~james/pygtk-docs/class-gdkpixbuf.html

Alternatively, if you have a pixbuf instance that contains your image
data, you can access the data as an RGBA array with

  # pb is a gtk.gdk.Pixbuf
  pa = pb.get_pixels_array()  #pygtk 2.2 and

or 
  
  pa = pb.pixel_array   # pygtk-2.0

You can then access the rgba components, eg

    pa[:,:,0]  # red
    pa[:,:,1]  # green
    pa[:,:,2]  # blue
    pa[:,:,3]  # alpha

and write them to a file anyway you want.

Or am I not understanding you?
