Comment 6 for bug 1626667

Thanks Olivier for your time and patience, I really appreciate.

Just installed the gallery-app package, but it isn't listed as content provider in the webapp-container nor in other webapps (g+, facebookmessenger...).
An image picker could be enought for a wiki webapp (essentially the majority of files uploaded in the italian wiki by users are images). If I need different types of files, I'll look to the ubuntu-filemanager-app, however first I need that webapp-container can see these apps.

Any idea on how to archieve this?
If ther's some kind of documentation I can read, please send me links.
