title: Javascript Phaser cross-origin error
body: <p>I made a game using html, javascript, and the Phaser library. It works perfectly fine on my localhost. However when I upload it to Github (via the web interface), and run it, it gives this error:</p>
  
  <blockquote>
    <p>Uncaught SecurityError: Failed to execute 'texImage2D' on 'WebGLRenderingContext': The cross-origin image at <a href="http://www.imagesup.net/dt-1514207740759.png" rel="nofollow noreferrer">http://www.imagesup.net/dt-1514207740759.png</a> may not be loaded.</p>
  </blockquote>
  
  <p>Could someone please explain what I'm doing wrong, and how to fix it?</p>
  
  <p>Thanks.</p>
