Welcome kmc (in the past, I've been working with public libraries because I've contributed to Koha).

At first read, I thought you wanted to have photo upload with no validation. This subject is discussed from time to time on the forum, and in the half dozen topics I've read to refresh my mind, there is no complete solution to this request.

But then I've read your post once again and I realize that you may be satisfied with multiple administrators. An administrator has access to the administration panel, so that he can "synchronize". To upload their photos, each of your administrator will need the FTP access to the gallery. It may be enough for your need.

With next version 2.0.0, comes pLoader a dedicated client for Piwigo (new name of PhpWebGallery). With pLoader, you can upload photos in any category. I think it's very near what you are looking for. I was not designed for multiple administrator, but can perfectly work this way. With current 1.7, FTP+sync is required.

Hello!

I have another question for you and this might be a silly one, but I am wondering if the latest version of this software works on the Windows XP operating system?
