How can i see image on build my ionic v2 app?


I encountered a problem with the build of my ionic application.
When I use ionic serve I see my image well in the application, but if I do the build then I could not see the image neither in the android and ios
i use the code with two different ways and no result with ionic build just in ionic serve i can see’t.
Code :

// page.html :
<div style="text-align: center" >   
<img  src="../assets/images/Barcodeicon.png"  (click)="click()" >
//pgae.scss :
	background-image: url('../assets/images/Barcodeicon.png');
