Show label and image when file is uploading

I would like to display a label and image when someone clicks the submit button to upload a file. I've been tinkering around with progress bars, but none seem to work correctly with the rest of my code. What I though I could do is simply show a label and image when someone clicks the button, however the label and image don't show up until after the upload takes place. I'm assuming this is because the click event for the browse button on a Fileupload control is the same as the button_click event I think. Anyway, below is the code I'm trying to use:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        btnProgress.Visible = False
        lblProgress.Visible = False
    End Sub

Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click


        'before submitting make sure there is a file
        If FileUpload1.HasFile Then
        btnProgress.Visible = True
        lblProgress.Visible = True

            SaveFile(FileUpload1.PostedFile)

        Else
            lblUploadResult.Text = "Your file was not uploaded properly, please try again or contact the webmaster at emailaddresshere."
        End If


    End Sub

    Sub SaveFile(ByVal file As HttpPostedFile)
       
        'Path where file is uploaded
        Dim savePath As String = System.Configuration.ConfigurationManager.AppSettings("UploadFolderHere")

        'Get name of client file and then extract extension
        Dim extension As String = FileUpload1.FileName
        Dim ext As String = System.IO.Path.GetExtension(extension)

        'name of file
        Dim fileName As String = txtPresNumber.Text & "_" & txtLastName.Text + ext



        'Create path and filename to check dups
        Dim checkPath As String = savePath + fileName

        'temp filename to check dups
        Dim tempFileName As String

        If (System.IO.File.Exists(checkPath)) Then
            Dim counter As Integer = 1
            While (System.IO.File.Exists(checkPath))
                tempFileName = counter.ToString() & "_" & fileName
                checkPath = savePath + tempFileName
                counter = counter + 1
            End While
            fileName = tempFileName

            lblUploadResult.Text = "Thank you very much, your file has been received."
        Else
            lblUploadResult.Text = "Thank you very much, your file has been received."

        End If

        'Append Name
        savePath += fileName

        'Call save as method
        FileUpload1.SaveAs(savePath)
