Hello.
I am new Piwigo user, i installed in my DNS320L to manage my personal photos, but I'm with a great difficulty.
I have +10k photos in over 100 directories in my NAS. Which is also installed Piwigo. I would like to synchronize the Piwigo gallery with the directory, as well as when I add a new photo in the directory, this update also in Piwigo base.
Already researched in the manual, and as the topics of the forum, including the forum of Brazil. Maybe I have not looked right then, because the only answer I got was to add a new site, indicating the directory of the photos, but always get error.

my photos are in the directory: /mnt/HD/HD_a2/Imagens


I would love to help you, so I can solve my problem.
