private void btn_extract_Click(object sender, EventArgs e)
{
    Image imgGif = Image.FromFile(@"test.gif", true);

    //Create a new FrameDimension object from this image
    var ImgFrmDim = new FrameDimension(imgGif.FrameDimensionsList[0]);

    //Determine the number of frames in the image
    //Note that all images contain at least 1 frame,
    //but an animated GIF will contain more than 1 frame.

    int n = imgGif.GetFrameCount(ImgFrmDim);

    // Save every frame into jpeg format
    for (int i = 0; i < n; i++)
    {
        imgGif.SelectActiveFrame(ImgFrmDim, i);
        imgGif.Save(string.Format(@"Frame{0}.png", i), ImageFormat.Png);
