MultipartMessage mpMessage = (MultipartMessage) conn.newMessage(MessageConnection.MULTIPART_MESSAGE);

// 填入header信息
mpMessage.setSubject("MMSMIDlet Image");

InputStream is = getClass().getResourceAsStream(mImageToSend);
byte[] bImage = new byte[is.available()];
is.read(bImage); //把图片变为byte数组

//加载数据包
mpMessage.addMessagePart(new MessagePart(bImage, 0, bImage.length,"image/png", "id1", "location", null));
conn.send(mpMessage); //发送
