title: angular 1: image won't reload after a while
body: <p>In my HTML I have this img link:
  </p>
  
  <p><strong>imgURL is set in the controller:</strong></p>
  
  <pre><code>$scope.imgURL = 'img/img_'+$scope.img.id+'.jpg;
  </code></pre>
  
  <p>With the first changes it works perfectly, but after a while the image doesn't show anymore..??</p>
  
  <p>I read an tried several "solutions" like adding a parameter with random value so it forces to reload, but it didn't work. I log the url in the console and see it changing, so that's not the point.</p>
  
  <p>What can cause the not appearing of the image after a while, it looks so random..? 
  Your answer is highly appreciated, I'm rather desperate :-/</p>
