image management code?

two days back i ask a question for image management, i get some reference that is 4guys the code is working fine i want to store that manged image in a folder but i not understand how can i save, can u help me. this is my code.....

public partial class Default2 : System.Web.UI.Page
{
    public bool ThumbnailCallback()
    {
        return false;
    }
    protected void Page_Load(object sender, EventArgs e)
    {

        System.Drawing.Image.GetThumbnailImageAbort dummyCallBack = default(System.Drawing.Image.GetThumbnailImageAbort);
        dummyCallBack = new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback);

        System.Drawing开发者_JAVA技巧.Image fullSizeImg = default(System.Drawing.Image);
        fullSizeImg = System.Drawing.Image.FromFile("C:\\05.jpg");

        System.Drawing.Image thumbNailImg = default(System.Drawing.Image);
        thumbNailImg = fullSizeImg.GetThumbnailImage(100, 100, dummyCallBack, IntPtr.Zero);


    }
}

To save an image to a folder on the server, call image.Save(path).

EDIT: You can send a smaller version of an image to the browser like this:

using(Image originalImage = something)
using(Bitmap smallImage = new Bitmap(originalImage, width, height)) {
    Stream stream = new MemoryStream();    
    smallImage.Save(stream);
    Response.OutputStream.Write(stream.ToArray(), 0, stream.Length);
}
