Answer 1

SQL doesn't need the double equal signs.
SELECT ImageName FROM dbo.ProfilePic WHERE Username = #UserName

Answer 2

in SQL you don't need to use double equal sign to compare values and && is wrong, then this is wrong:
string querystring = "select ImageName from dbo.ProfilePic where UserName == #UserName && IsActive == 'Y' order by ID descending";
and this is true:
string querystring = "select ImageName from dbo.ProfilePic where UserName = #UserName AND IsActive = 'Y' order by ID desc";

Answer 3

string querystring = "select ImageName from dbo.ProfilePic where UserName =
#UserName AND IsActive = 'Y' order by ID DESC";
// on sql compare oprator not need to '==' sign
SqlCommand command = new SqlCommand(querystring, con);
command.Parameters.AddWithValue("#UserName", Session["UserName"].ToString());
con.Open();
SqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{
Console.WriteLine(String.Format("{0}",
reader[0]));
// when you assign reader value to any object you must assign while DataReader read not after DataReader close
ViewBag.ProfilePic = reader[0];
}
reader.Close();
EDIT
try
string querystring = "select ImageName from dbo.ProfilePic where UserName like '#UserName' AND IsActive = 'Y' order by ID DESC";
