open file from client, get the byte of array then save to server

Question

Dear friend,

As you know that ASP .NET has client side and server side...
it means that we can get and open a file from client (C:\jaguar.jpg) then get the byte of array, then we save it to the server (Server.MapPath(Request.ApplicationPath) & "\Images\HORE.jpg")...
i tried the following code, but it does not work properly when we open the file from client...
Pls help...
Thank you,
hendy

                Dim s As Stream = File.OpenRead("C:\jaguar.jpg")
                Dim buffer(s.Length) As Byte
                s.Read(buffer, 0, CType(s.Length, Integer))
                Dim len As Integer = CType(s.Length, Integer)
                s.Close()
                Dim fs As FileStream = New FileStream(Server.MapPath(Request.ApplicationPath) & "\Images\HORE.jpg", FileMode.Create)
                fs.Write(buffer, 0, len)
                fs.Close()
