how can i show picture in picturebox on regular interval and store in database ?

private void Form_Load(object sender, EventArgs e)
{
    moveTimer.Interval = 1000;
    moveTimer.Tick += new EventHandler(moveTimer_Tick);
    moveTimer.Start();
}
private void moveTimer_Tick(object sender, System.EventArgs e)
{
    string[] images = Directory.GetFiles(@"C:\Dir", "*.jpg");
    image = Image.FromFile(images[counter]);
    pictureBox.Width = image.Width;
    pictureBox.Height = image.Height;
    pictureBox.Image = image;

    // Move Image to new location
    pictureBox2.Left = rand.Next(Math.Max(0, Bounds.Width - pictureBox.Width));//////ERROR ERROR 
    pictureBox2.Top = rand.Next(Math.Max(0, Bounds.Height - pictureBox.Height));////ERROR ERROR 

    if (counter < images.Count - 1)//ERROR OPERATOR - CANnot be applied to operands of type method group and int
    {
        counter = counter + 1;
    }
    else
    {
        counter = 0;
    }
}
