title: CORS issue using create-react-app when trying to use an image from another URL
body: <p>I normally create my react projects with a static express server but figured I would give create-react-app a shot. </p>
  
  <p>However I am running into an issue with my current project. 
  When trying to use an img tag in the react code and use the src URL from another site I get a CORS issue.  </p>
  
  <p>"Access to image at '<a href="http://www.dailygarnish.com/wp-content/uploads/2012/04/IMG_20120414_205845-640x640.jpg" rel="nofollow noreferrer">http://www.dailygarnish.com/wp-content/uploads/2012/04/IMG_20120414_205845-640x640.jpg</a>' from origin '<a href="http://localhost:3000" rel="nofollow noreferrer">http://localhost:3000</a>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."</p>
  
  <p>This works perfectly fine normally on Apps where I created the server, but not with create-react-app</p>
  
  <p>Any advice would be appreciated</p>
