byte[] to bufferedImage i en cellrender uden det bliver grimt

Problemet er at billedet bliver MEGET grimt.

Billedet bliver sendt fra server til klient i et byte[].
Dette byte[] er pakke ind i et object der hedder Mana

public class CostCellRender extends JComponent implements TableCellRenderer  {
  private BufferedImage image;

  public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int rowIndex, int vColIndex) {
    Vector costs = (Vector)value;
    image = new BufferedImage(25, 25, BufferedImage.TYPE_BYTE_BINARY);
    JPanel panel = new JPanel();
    panel.setBackground(Color.WHITE);
    for(int q = 0; q < costs.size(); q++){
      Mana mana = (Mana)costs.elementAt(q);
      ByteArrayInputStream i = new ByteArrayInputStream(mana.getPicture());
      try{
      image = ImageIO.read(i);
      }
      catch(Exception x){
        x.printStackTrace();
      }
      //image = ImageIO.read();
      ImageIcon icon = new ImageIcon(image);
      JLabel label = new JLabel(icon);
      panel.add(label);
    }
    return panel;
  }
}
