Les comparto mi codigo

            Dim htmlDocument As HtmlDocument = Me.WebBrowser1.Document
            Dim prueba As String = htmlDocument.GetType.ToString
            Dim htmlElementCollection As HtmlElementCollection = htmlDocument.Images
            Dim ImagesFound As Integer
 
            For Each htmlElement As HtmlElement In htmlElementCollection
                Dim imgUrl As String = htmlElement.GetAttribute("id")
                If imgUrl = "BtnDescarga" Then
                    imgUrl = Replace(htmlElement.OuterHtml, Chr(34), "")
                    ImagesFound = InStr(imgUrl, "','Recuperacion')")
                    imgUrl = imgUrl.Substring(103, ImagesFound - 104)
                    imgUrl = "https://portalcfdi.facturaelectronica.sat.gob.mx/" & imgUrl
                    ListBox1.Items.Add(imgUrl)
                End If
            Next
 
            Dim URI, archivo As String
            Dim wc As New WebClient
 
            wc.Headers.Add(HttpRequestHeader.Cookie, GetGlobalCookies(WebBrowser1.Document.Url.ToString))
 
            For i = 0 To ListBox1.Items.Count - 1
                URI = ListBox1.Items.Item(i).ToString.Trim
                wc.DownloadFile(URI, ruta a guardar)
next
