ng-src is not working correctly
<p>I am building a mobile app using Ionic Framework 1 &amp; AngularJS</p>

<p>I have REST service returning JSON data. The data is a photo album which consists of a name and an array of images in the album. I would like to use nested ng-repeat to display the albums and their photos in a view.</p>

<p>So ng-repeat is correctly iterating over the 2 albums &amp; 4 images in each but the images are not displaying, upon inspecting elements, ng-src="0". What's going on &amp; how do I fix this?</p>
