ช่วยดู Error ตัวนี้ทีครับ "Value of type 'System.web.UI.Control' cannot be converted to 'System.Drawing.image'

    Protected Sub DataList1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles DataList1.ItemDataBound
        Dim image As Image = CType(e.Item.FindControl("Picture"), Image)
        If Not IsNothing(image) Then
            image.imageurl = "Thumpnail/" & image.imageurl
        End If
    End Sub
