I don't want to break the API mapping. Maybe it is possible to add a
pygtk only method (If I remember correctly there are already such methods
for treeviews).
For example a gtk.Image.set_from_file_object()

You are right, the solution is PixbufLoader it can take a buffer and
write it to a pixbuf.
Maybe the the gtk.Image.set_from_file_object() could be a wrapper for
this solution. Something like this:
def set_from_file_object(self,file_object,image_format=None):
buffer=file_object.read()
pixbuf_loader=gtk.gdk.PixbufLoader(image_format)
pixbuf_loader.write(buffer)
pixbuf_loader.close()
pixbuf=pixbuf_loader.get_pixbuf()
self.set_from_pixbuf(pixbuf)
