(Pictures) gallery updated

I have updated the (pictures) gallery to the latest version of Coppermine (the gallery software that I use here). I have also re-enabled the comment function in the gallery. Note that user registration in the gallery has been disabled now (as well as here on the main page) as I don't think there is any need for registration in the gallery. I also have removed all the users that had registered for the gallery (none of them has logged into the gallery for at least four years anyway).
