Any Piwigo photo gallery can have a specific home page, with any content on it. Just use the Additionnal Pages plugin and set a page as homepage.
We have received some emails on Piwigo.com support because the breadcrumbs were not including the albums root: Home / Album level 1 / Album level 2. With a specific home page, the “home” links goes to it. In practice you had to go back to home page to return on albums root.
We have just added a small feature: if you have an home page defined with Additional Pages, then the breadcumbs includes the albums root: Home / Albums / Album level 1 / Album level 2.
