Opdater billed løbende

Jeg har en server applikation som opretter en \"client worker\" (anden klasse som håndterer indkomne klienter). client worker modtager en fil som skrives på HD (x.jpg)

problemet er at jeg gerne vil kunne vise billedet på skærmen (i \"frame\") hver gang der modtages et nyt billede fra klienterne...

Koden ser således ud:
import java.awt.Color;
import java.awt.BorderLayout;

  private Socket client; 
     
  ClientWorker(Socket client) {
  this.client = client;     
  }

  public void run(){
    String line;
    int readValue;
    InputStream in = null;
    PrintWriter out = null;
    int fileSize = 0;
    try{
      in = client.getInputStream();       
      out = new PrintWriter(client.getOutputStream(), true);
    } catch (IOException e) {
      System.out.println(\"in or out failed\");
      System.exit(-1);
    }

    try{
      int c;
      int i = 0;             
      int count = 0;
         
      while (count < 4){
        c = in.read();
        fileSize += c<<i; // the received byte is multiplied with 2 to the i in order to convert from hex value
        i+=8;
        count++;
      }
      // just for verification
      System.out.println(\"file size: \" +  fileSize);    

      BufferedInputStream bin = new BufferedInputStream(in);
      FileOutputStream fo = new FileOutputStream(\"xxxx.jpg\", false);

      count = 0;
      c = bin.read();
      while ((count < fileSize) & (c != -1)){
        fo.write(c);
        count++;
        c = bin.read();
      }

      System.out.println(\"Bytes read \" + count);
      fo.flush();
      fo.close();
      in.close();

    } catch (IOException e) {
