You get it, the objective of the gallery section is to allow you to display images in your app. And you can have millions of reasons to display images! Here are 2 specific examples.

A gallery to illustrate the life of a school

We created the Paraigua app which is an app for a school. Its role is to communicate important information to its students but also to parents, and to create a real community around the school. We’ve inserted a Gallery section, in which photos of the life of the school are regularly published, such as events between students.
To contextualize the pictures, we have chosen a template that lets the title and description of each picture appear.
