Can I have a custom image/file folder in the "app" folder that can appear also in emulator

For some uncontrolled reason (JSON feed has HTML integrated), I have to have a custom folder with images and files in my app folder apart from /images/ folder.

The problem: Although it shows in the browser, it is not imported to iOS build when I build the project. Is there a way I can have it detected too?

I am using Ionic.


Neither custom CSS or nor custom Image folder is detectable.
