To upload the file:

http://msdn.microsoft.com/en-us/library/aa446517.aspx

And delete the file

System.IO.file.Delete(strPath)

Thanks for the quick response , I have added the following to my solution

Public Sub UploadFile(ByVal localFile As String, ByVal uploadUrl As String)
        Dim req As HttpWebRequest = CType(WebRequest.Create(uploadUrl), HttpWebRequest)
        req.Method = "PUT"
        req.AllowWriteStreamBuffering = True
        ' Retrieve request stream and wrap in StreamWriter
        Dim reqStream As Stream = req.GetRequestStream()
        Dim wrtr As StreamWriter = New StreamWriter(reqStream)
          ' Open the local file
        Dim rdr As StreamReader = New StreamReader(localFile)
          ' loop through the local file reading each line
        '  and writing to the request stream buffer
        Dim inLine As String = rdr.ReadLine()

        While Not inLine Is Nothing
            wrtr.WriteLine(inLine)
            inLine = rdr.ReadLine()
        End While

        rdr.Close()
        wrtr.Close()

        req.GetResponse()
    End Sub

an a  button with

UploadFile((Path.Combine(AppPath, job_no + "CapturedSignature1.bmp")), uploadurl)

do I need to do anything else as it seems to be getting stuck around the      Dim inLine As String = rdr.ReadLine() and the error message on the mobile device is

ioexception
an error message cannot be displayed because an optional resource assembly containing it cannot be found

at system.IO._error.winIOerror()
at system.io.file.delete()

etc

did you try debugging the code?

Put a breakpoint on that line and mouse over the text. It shoud give you the value
