> VB2005にてサイトのアイコン(favicon.pngイメージ)をwebbrowserで取得したいのですが、

favicon.icoではないのですか？
favicon.icoなら例えば次のように取得できます。（webbrowserではありませんが...)

Imports System.Net
Imports System.IO

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.WebBrowser1.GoHome()
    End Sub

    Public Function GetFavicon(ByVal Url As String) As Image
        Dim Img As Image = Nothing
        Dim Req As WebRequest = Nothing
        Dim i As Integer = Url.LastIndexOf("/")
        Url = Url.Substring(0, i) & "/favicon.ico"
        Try
            Req = WebRequest.Create(Url)
            Using myResponse As WebResponse = Req.GetResponse()
                Using myStream As Stream = myResponse.GetResponseStream()
                    Img = Image.FromStream(myStream)
                End Using
            End Using
            Return Img
        Catch ex As Exception
            Return Nothing
        End Try
    End Function

    Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
        Dim f As New Form
        f.BackgroundImage = GetFavicon(e.Url.ToString)
        f.Show()
    End Sub

End Class
