AngularJS Built-in directives ngSrc
Example
Using Angular markup like {{hash}} in a src attribute doesn't work right. The browser will fetch from the URL with the literal text {{hash}} until Angular replaces the expression inside {{hash}}. ng-src directive overrides the original src attribute for the image tag element and solves the problem
<div ng-init="pic = 'pic_angular.jpg'">
<h1>Angular</h1>
<img ng-src="{{pic}}">
</div>
