My solution is:
def save( self ):
if self.image1:
original = Image.open( self.image1 )
if original.mode not in ('L', 'RGB'):
original = original.convert('RGB')
cp_image = original.copy()
cp_image_handle = StringIO()
cp_image.save( cp_image_handle, 'JPEG', quality=100 )
cp_image_handle.seek(0)
cp_image_upload =
SimpleUploadedFile(os.path.split(self.image1.name)[-1],cp_image_handle.read(),
content_type='image/jpeg')
self.image1.save( "changed_extension.jpg", cp_image_upload, save=False)
super( MyModel , self ).save()
