请大家帮我看看这段程序到底是那里有错，先谢谢了啊
 System.Drawing.Image image, newImage;
        int width, height, newWidth, newHeight;
        System.Drawing.Image.GetThumbnailImageAbort callB = null;
        image = System.Drawing.Image.FromFile(Server.MapPath("images/1.jpg"));
        width = image.Width;
        height = image.Height;
        if (width > height)
        {
            newWidth = 100;
            newHeight = height / width * 100;
        }
        else
        {
            newHeight = 100;
            newWidth = width / height * 100;
        }
        newImage = image.GetThumbnailImage(newWidth, newHeight, callB, new System.IntPtr());
        newImage.Save(Server.MapPath("images/1s.jpg"));
        newImage.Dispose();
        image.Dispose();

老是提示说内存不足，请大家指点
