I have installed Piwigo,
Good points:
- Installation and configuration is extremely easy.
- Upload templates is easy.
- Generate content is also very intuitive.
Bad points:
- The time response is not good. The issue is not Piwigo, I would point to the hosting service I have for that, but this is a relevant point for an user visiting the pictures gallery.
- The look & feel of the templates does not belong to the latest generation of web, and for the look we are required we need to perform it with a better look.
I see it is a good tool, but not for the special needs I have 🙁
