This is the main parent task for all work related to retrieval of image file lists from categories. The resulting image list is cycled though on the {T221927}
Category contents will be retrieved **live** at the time the user enters the Participate Campaign page. This will allow any recent additions/changes to the category contents to be reflected in the list shown to the user.
The list of images generated does **not ** need to be available after the user exits the current participation session.
**ROADMAP**
**1. ISA Initial test version:**
The initial implementation is a simplified version of the feature, which will enable us to begin testing the participate campaign page and start work on system for storing contributions in the database.
- T222231 A single combined list of image files is generated from all Campaign categories, //without // looking into any subcategories
**2. ISA Minimum Viable Product:**
Extend functionality to reach the minimum functionality we would need for an initial 'complete' working version of the app.
- T222262 Include a depth of subcategories (which will be specified by the manager when creating the campaign)
- T222265 For **Wiki Loves campaigns only**, extract a list of all country sub-categories which will be used to populate the dropdown option on the Campaign page (i.e. the user can optionally select a single country to work when participating)
