title: Correct way to use image assets in Ionic 2
body: <p>What’s the best practice for image assets in Ionic 2? I have a bunch of SVGs I want to use as non-system icons. I found some older tips on using Gulp but it seems Ionic team has decided on Rollup as the build tool of choice, no docs on this so far.</p>
  
  <p>Somebody told me to just add them to <code>www/img</code>. Any downsides?</p>
