不得已
  还是采用了Manipulator


def thumbnail(content):
    size = (48,48)
    image = Image.open(content)
    image = image.convert('RGB')
    image = image.resize(size)
    return image



class ImageManipulator(forms.Manipulator):

    def __init__(self, request=None):
        self.request = request
        self.fields = [
            forms.ImageUploadField(field_name="icon"),
        ]

    def save(self, group):
        file_obj = self.request.FILES.get('icon', None)
        if file_obj:
            path, ext = os.path.splitext(file_obj['filename'])
            if group.icon:
                filename = group.get_icon_filename()
                if os.path.exists(filename):
                    try:
                        os.remove(filename)
                    except:
                        pass
            group.save_icon_file(self.user.id + ext,
thumbnail(file_obj['content']))
        group.save()

可是最终上传总会:No file was submitted. Check the encoding type on the form.

这是个什么原理呢?  我分别用jpg和BMP格式实验了  还是不行 不知道为什么
