Instead of mirroring the image repeatedly, keep a reference to images facing both ways and set them to the actor when needed.

So would it be something more like this 
 private GreenfootImage rightImage;
    private GreenfootImage leftImage;
    public Human()
    // This just difines what rightImage and leftImage are so they can be used later in the code
    {
        rightImage = new GreenfootImage ("HumanRight.gif");
        leftImage = new GreenfootImage ("HumanLeft.gif");
    }

    public void act() 
    {
        move();
    }

    public void move()
    // This is where the character is controlled it makes it so the character face the right way
    {
        if (Greenfoot.isKeyDown("s"))
        {
            setLocation(getX(), getY() +2);
        }

        if (Greenfoot.isKeyDown("w"))
        {
            setLocation(getX(), getY() -2);
        }

        if (Greenfoot.isKeyDown("a"))
        {
            setImage("leftImage");
            move(-2);
        }

        if (Greenfoot.isKeyDown("d"))
        {
            setImage("rightImage");           
            move(2);            
        }
    }
