You need first to serialize the object to bytes that can go over the wire. There is no predefined way to do that, so you can: >>> import io >>> file_like_object = io.BytesIO() >>> PILImage.save(file_like_object, format='png') and then in your POST request send file_like_object.getvalue() as the image data. You will most probably need to add a Content-Type: image/png as a header. -- https://mail.python.org/mailman/listinfo/python-list
