Use assets folder for my image

Hello guys,

I try to put assets folder my own image for use that in one page, but this folder exist without the image in cordova build.

Folder structure (projectname/src/):

Immagine

Folder from console of app:
Immagine


For now I’ve solved it using a base64 image instead of the physical image, but if you have any better advice, I’m here.
