Hello, a friend photographer recommended Piwigo, I had a look at the website, but I'm really not computer savvy and I still don't really understand how it works. Could someone explain to me in simple words ? Or would it be too complicated for me to use ?

I have  about 100 000 photos on an iMac which I will need access to for a few months from a Mac Book. The idea is to have all the photos on an external hard drive and then a software I can use on my laptop to visualise them in a gallery without having to download them as my laptop doesn't have enough space for that.

Thank you
Bernadette
