SlideShow C#

zwartfrak

I am making a program for a slideshow in C#
this is the code that causes problems :

Expand|Select|Wrap|Line Numbers

 
    private void btnPlay_Click(object sender, EventArgs e)

        {

            for (int a = 0; a < iAmountOfImages; a++)

            {

                pbSlideshow.SizeMode = PictureBoxSizeMode.Zoom;

                pbSlideshow.Image = new Bitmap(sImage[a]);

                System.Threading.Thread.Sleep(2000);

            }

        }

The problem is: It shows my first image: sImage[0] and after some time, it shows the last image, but i don't see the other images.
