Timer.Tick doesn't work

I'm trying to move image on the panel with timer.tick but it doesn't work for some reason... Timer is enabled in properties window and this is my code:

public partial class Form1 : Form
{
    private Image img;
    private Point pos;

    public Form1()
    {
        InitializeComponent();

        img = Image.FromFile("C:/object.png");
        pos = new Point(100, 100);
    }

    private void panel1_Paint(object sender, PaintEventArgs e)
    {
        e.Graphics.DrawImage(img, pos);
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        pos.X += 10;
        pos.Y += 10;

        Invalidate();
    }
}

I can't see what is the problem here?? :)

I also tried this:

public partial class Form1 : Form
{
    private Image img;
    private Point pos;

    public Form1()
    {
        InitializeComponent();

        img = Image.FromFile("C:/object.png");
        pos = new Point(100, 100);

        Timer myTimer = new Timer();
        myTimer.Enabled = true; // don't know if this goes here
        myTimer.Tick += new EventHandler(MoveImg);
        myTimer.Interval = 100;
        myTimer.Start();
    }

    private void MoveImg(Object myObject, EventArgs myEventArgs)
    {
        pos.X += 10;
        pos.Y += 10;

        Invalidate();
    }

    private void panel1_Paint(object sender, PaintEventArgs e)
    {
        e.Graphics.DrawImage(img, pos);
    }
}

You need to start the timer using Timer.Start() 

public Form1()
{
    InitializeComponent();

    img = Image.FromFile("C:/object.png");
    pos = new Point(100, 100);
    timer1.Start();
}

And as Hans Passant says - you have to Invalidate the right object. 

private void MoveImg(Object myObject, EventArgs myEventArgs)
{
    pos.X += 10;
    pos.Y += 10;

    panel1.Invalidate();
}
