As is, there is no way to determine which image was last set to the actor. You will probably need to add a field so you can track the last direction set. Easiest would be an int field, giving it values of 0 through 3, for right, down, left and up (facing angle divided by 90). Then, when you create a bullet, you can follow up with setting its direction properly: 
Actor bullet = new Bullet();
bullet.setRotation(90*<< direction value >>);
getWorld().addObject(bullet, getX(), getY());

Yeah: 
private int facingDir;

public void act()
{
    if (Greenfoot.isKeyDown("d")){
        setLocation(getX()+5, getY());
        setImage("pixil-frame-0.png");
        facingDir = 0;
    }
    // etc.
}
