I am complete newbie to piwigo, I have been given a task to upload Nearly 90,000 articles.
these articles are sorted and saved to system acc to categories on Desktop.I have been given a piwigo test instance to study and find the useful plugins which would ease my work.

I have installed some plugins and studying them, technical dept. member told  that,  by installation of more number of plugins , system may destabilize.

Can installation of more number of plugins, destabilize the system?

I had read that by using FTP synchronization we can upload many articles at once,but I dont know how to use it , can anyone brief me with a small example or short steps??

Thnx in advance…...
