How to get/download the album art from internet for music player project

Hello i'm making Music player with clean look and great design and i'm about to finish it but i want to add a cool smart feature is when there is an internet connection and there isn't album cover in the mp3 file ('The song) then the program should download and get the cover by name of the mp3 file and if there is cover in the mp3 file use it (i already done that). all i wan't knew is to knew what i done wrong in this code. The problem is Msgbox appearing and says error in downloading song cover BUT why. Is there is something wrong in my code? and thanks for you time and helping me :)

If My.Computer.Network.IsAvailable Then

       Label13.Text = Label5.Text
       Dim Clint As New WebClient()
       Dim photolink As String = Nothing

       Application.DoEvents()
       Dim sourceCollection As String = Clint.DownloadString(New Uri("https://www.amazon.com/s?k=" + Label13.Text + "&i=digital-music&ref=nb_sb_noss"))
       Dim Weber As New WebBrowser With {.ScriptErrorsSuppressed = True}
       Weber.DocumentText = sourceCollection
       Dim htmlColl As HtmlDocument = Weber.Document.OpenNew(True)
       htmlColl.Write(sourceCollection)
       If htmlColl.GetElementById("mp3StoreShovelerCell0") IsNot Nothing Then
           Dim theHtmlElementCollection As HtmlElementCollection = htmlColl.GetElementById("mp3StoreShovelerCell0").GetElementsByTagName("img")
           For Each curElement As HtmlElement In theHtmlElementCollection
               photolink = curElement.GetAttribute("src")
           Next
           If photolink IsNot Nothing Then
               photolink = photolink.ToString.Replace("._SL500_SS110_.jpg", "._SS500_.jpg")
               BunifuImageButton2.ImageLocation = photolink



           End If
       Else
           BunifuImageButton2.Image = My.Resources.clipart536736

           MsgBox("Error in Downloading Song Cover")

       End If

   Else

       If (file.Tag.Pictures.Length > 0) Then

           BunifuImageButton2.Image = Image.FromStream(New MemoryStream(bin)).GetThumbnailImage(600, 600, Nothing, IntPtr.Zero)

           BunifuImageButton7.Image = Image.FromStream(New MemoryStream(bin)).GetThumbnailImage(600, 600, Nothing, IntPtr.Zero)

       End If
   End If
