Changes

There was a problem also with png extensions, which has been fixed now. File pages were previously automatically redirected to the photo display page without the meta data info, like [https://www.madacamp.com/File:Hotel_Palma_Nova_004.jpg File:Hotel_Palma_Nova_004.jpg] -> [https://www.madacamp.com/photo.cgi?Hotel_Palma_Nova_004.jpg https://www.madacamp.com/photo.cgi?Hotel_Palma_Nova_004.jpg] but the photo display was not made considering all file endings, so the automatic redirect been removed.
