Angular 4 to 8
Either works
<img [src]="imageSrc" [alt]="imageAlt" />
<img src="{{imageSrc}}" alt="{{imageAlt}}" />
and the Component would be
export class sample Component implements OnInit {
imageSrc = 'assets/images/iphone.png'
imageAlt = 'iPhone'
Tree structure:
-> src
-> app
-> assets
-> images
'iphone.png'
