Photos in JPanel

Question

I am trying to write an application in which I want to add different drawings to Jpanel. Everything works fine except for the JPG format, which displays images with very poor quality. This is how I draw the picture:

class draw extends Canvas 
{
    Dimension canvasSize = new Dimension(400, 400);
    String fileName;

    public void paint(Graphics g) 
    {       
        if(this.fileName!=null)
        {
            Toolkit toolkit = Toolkit.getDefaultToolkit();
            Image img = toolkit.getImage(fileName);
            g.drawImage(img, 0, 0, this);
        }                   
    }
    public void setFileName(String name)
    {
        this.fileName=name;
    }

    public Dimension getMinimumSize()
    {
        return canvasSize;  
    }

    public Dimension getPreferredSize()
    {   
        return canvasSize;
    }
}

Is there a way that JPG format is covered?
