EmberJS Nested routes pictures doesn't load

I have ember.js application.

root /app /components /templates /gallery application.hbs gallery.hbs index.hbs app.js index.html router.js /public /assets --folders with pictures inside which contains pictures

I have 4200/gallery

Which load up pictures without ANY problems.

But in 4200/gallery/nested

It gives me:

GET http://localhost:4200/assets/bb/1.jpg 404 (Not Found)

Where is the problem please ? What do I do wrong it's frustrating that it does load without a problem on gallery page but it doesn't laod up on nested route.

It keeps me away from finishing this project.

Thank you for any answers.
