Green Veined Butterfly

Today my identification capabilities have been put to the test again with this little fellow. At first I thought it must be a 'Small White' as it had the same markings as a Large White but a lot smaller. But on further research I found that Small White's don't have the same vein markings as this one does. Sooooooo I think I've decided its a Male Green Veined Butterfly, I think.
