Send email with html and images over Sockets

Question

Hi! I'm sending email messages through sockets with html. So far is working great. But now, I need to include images in the html code, like a web page. I don't have any idea on how to do this. Sending image apart from the html code is not big deal, but how to put it in the code. I mean how to make this html code, work:
<table border="0">
     <tr>
          <td>Image in code</td>
     </tr>
     <tr>
          <img src="what to put here"/>
     </tr>
</table>This is the code that I'm using to send the html mail:
StringBuffer retBuff = new StringBuffer();
          //BufferedReader msg;
          //msg = new BufferedReader(msgFileReader);
          smtpPipe = new Socket(mailHost, SMTP_PORT);
          smtpPipe.setSoTimeout(120000);
          if (smtpPipe == null) {
               return retBuff;
          inn = smtpPipe.getInputStream();
          outt = smtpPipe.getOutputStream();
          in = new BufferedReader(new InputStreamReader(inn));
          out = new PrintWriter(new OutputStreamWriter(outt), true);
          if (inn == null || outt == null) {
               retBuff.append("Failed to open streams to socket.");
               return retBuff;
          String initialID = in.readLine();
          retBuff.append(initialID);
          retBuff.append("HELO " + localhost.getHostName());
          out.println("HELO " + localhost.getHostName());
          String welcome = in.readLine();
          retBuff.append(welcome);
          retBuff.append("MAIL From:<" + from + ">");
          out.println("MAIL From:<" + from + ">");
          String senderOK = in.readLine();
          retBuff.append(senderOK);
          for (int i = 0; i < to.length; i++) {
               retBuff.append("RCPT TO:<" + to[i] + ">");
               out.println("RCPT TO:<" + to[i] + ">");
               String recipientOK = in.readLine();
               retBuff.append(recipientOK);
          retBuff.append("DATA");
          out.println("DATA");
          out.println("From: Steren <" + from + ">");
          out.println("Subject: " + subject);
          out.println("Mime-Version: 1.0;");
          out.println("Content-Type: text/html; charset=\"ISO-8859-1\";");
          //out.println("Content-Type: multipart/mixed; charset=\"ISO-8859-1\";");
          //out.println("Content-Transfer-Encoding: 7bit;");
          //String line;
          //while ((line = msg.readLine()) != null) {
          //     out.println(line);
          out.println(msg);
          retBuff.append(".");
          out.println(".");
          String acceptedOK = in.readLine();
          retBuff.append(acceptedOK);
          retBuff.append("QUIT");
          out.println("QUIT");
          return retBuff;

Throw all this away and use one of the numerous existing Java mail packages, such as javax.mail for a start.
