Does your ASP.Net process (or the user if you are using impersonation) have permission to write to the directory?

see I have tested your code it's working, but it image and graphics need to dispose\

String ext = Path.GetExtension(fileAttach.PostedFile.FileName);
           string fn = DateTime.Now.ToString("yyyyMMddHHmmssffff");
           int width = 760;
           int height = 760;
           Stream stream = fileAttach.PostedFile.InputStream;
           Bitmap image = new Bitmap(stream);
           Bitmap target = new Bitmap(width, height);
           Graphics graphic = Graphics.FromImage(target);
           graphic.DrawImage(image, 0, 0, width, height);
           // A generic error occurred in GDI+. //occuring here
           graphic.Dispose();
           image.Dispose();
           //
           target.Save(Server.MapPath("~\\Site-Content\\Uploaded_Photo\\" + fn + "" + ext));

I guess this is one of the strange errors that exist for a very long time. Try to save the image to a stream, and write that stream to a file.

C#

using (MemoryStream outStream = new MemoryStream()){
    target.Save(outStream);
    outStream.Seek(0, SeekOrigin.Begin);
    using (FileStream fileStream = new FileStream("path\to\file",
           FileMode.Create, FileAccess.Write))
    {
        outStream.CopyTo(fileStream);
    }
}

thanks its working....may i know that what the need of MS & FS here...?

To be honest, I don't know. There's some slight difference between the memory stream and the stream created to write to a file, which is why the original way you used doesn't work while is seems to be file.
