I am not sure why but I am trying to make an image button and the URL's come from getting a JSON object in my controller, but what ever the link is through an error, and if I change it to works fine!!!
Controller:
$scope.iconImage = 'http://cdn.sstatic.net/stackoverflow/img/apple-touch-icon.png';
HTML:
<!-- Error: [$sce:insecurl] Blocked loading resource from url not allowed by $sceDelegate policy. -->
<input type="image" ng-src="{{iconImage}}" />
<!-- This works fine -->
<img ng-src="{{iconImage}}" />
