Hi

Sub Parser_StartElement(Uri As String, Name As String, Attributes As Attributes)
    If Attributes.Size > 1 Then
        imglink = Attributes.GetValue(2)      
    End If
End Sub

You shouldn't use GetValue if you want your app to be reliable. Use GetValue2 with the correct name. It will return an empty string if there is no such attribute.
