Image Get Requests with AngularJS
Try replacing your src with ng-src for more info see the documentation:
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}}. The ngSrc directive solves this problem.
<div ng-controller="Cont"> <img ng-src="{{imageSource}}"> </div>
If someone is searching the solution for styling background-image then use this:
<div ng-style="{'background-image': 'url({{ image.source }})'}">...</div>
