hi all, I assume it is a stupid newbie question, but I want/must avoid to loose or double my data....

so I have a family home server at home hosting videos, documents, and pictures. So I thought installing piwigo would be a good idea to effectively manage my close to 90.000 pictures while using the pictures that are on the server already......

now I read in the forum that I have to "transfer" the pictures to the server (even they are there already) and they will become renamed and ....
So basic question: is this the right way to go? will the data be doubled (which wouldn't work)? or did I miss the point?

So far I am managing the pictures via samba and dnla, but piwigo would be a great/ professional alternative to use the html interface.

any help appreciated!
