upload image working in localhost , but on server not

I have a site with upload image, on localhost working, but when I deploy it to server not working give me this error

Error! Object reference not set to an instance of an object

this is the method,

public string Createcontant(string articalname, string KEYWORD_NAME, string articalbody , HttpPostedFileBase file)
{
Contant c1 = new Contant() ;
OracleConnection conn = new OracleConnection();
OracleCommand cmd = new OracleCommand();
int MaxContentLength = 1024 * 1024 * 3; //3 MB
string[] AllowedFileExtensions = new string[] { ".jpg", ".gif", ".png", ".pdf" };
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(HttpContext.Current.Server.MapPath("~/Images"), fileName);
file.SaveAs(path);
try
{
conn.ConnectionString = ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString;
cmd.Connection = conn;
conn.Open();
cmd.Parameters.AddWithValue("photo", fileName);
cmd.Parameters.AddWithValue("articalname", articalname);
cmd.Parameters.AddWithValue("KEYWORD_NAME", KEYWORD_NAME);
cmd.Parameters.AddWithValue("articalbody", articalbody);
cmd.Parameters.AddWithValue("parAddedUser", HttpContext.Current.Session["UserName"].ToString());
cmd.Parameters.AddWithValue("articalbody", articalbody);
string sql = "insert into contact" +
"( ARTICL_ID, ARTICAL_NAME, IDATE, IUSER," +
" KEYWORD_NAME, ARTICALBODY ,photo )" +
" Values " +
"( CONTANT_SEQ.nextval, :articalname,sysdate,:parAddedUser," +
" :KEYWORD_NAME,:articalbody , :photo)";
cmd.CommandText = sql;
cmd.ExecuteNonQuery();
cmd.Dispose();
cmd.Parameters.Clear();
return "done";
}

where is the problem?

Hi,
I think this is the line
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(HttpContext.Current.Server.MapPath("~/Images"), fileName);
giving exception.
Can you Please put the code in try catch and change the code like below
var path = Path.Combine(HttpContext.Current.Server.MapPath("~/Images"), fileName);
var fileName = path.GetFileName(file.FileName);

1. var fileName = Path.GetFileName(file.FileName);
2. var path = "~/images/" + fileName ;
3. file.SaveAs(HttpContext.Server.MapPath(path));
