    Hi.
    Write your code like this,
    if (FileUpload1.HasFile)
    {
    string extension = System.IO.Path.GetExtension(FileUpload1.FileName);
    if (extension == ".jpg" || extension==".png" || extension==".gif")
    {
    FileUpload1.SaveAs("yourpath" + FileUpload1.FileName);
    }
    else
    {
    Response.Write("Select Correct file format");
    }
    }
    thanks
