We are really close to landing enough of the content-hub for you to be able
to make that work.  To pull pictures from other apps, you would use the
content-hub API to get the default peer for pictures, which is gallery-app
and provides the UI for picking pictures and returns them back to your app.
 You can also query all known peers that can provide pictures as well.

Your app could also be registered as a known provider for pictures, which
would allow other apps to find them.  To do this you would need to
implement an export handler, which provides the UI to browse and pick.
 There is also currently work underway to provide a default SDK component
that could be used for picking.

I really hope we can land all the necessary bits to make this work with app
confinement this week.  You can find code examples in the content-hub
source:

Thanks,
