Chrome Packaged Apps Resource Loader

You can request external images using XMLHttpRequest and transform them into ObjectURLs. Then set the src attribute in the <img> tag to each ObjectURL and it should work.

Since this is a very common use case, we created this library to simplify it. Just drop the apps-resource-loader ral.min.js to your project and then:

var remoteImage, 
    container = document.querySelector('.imageContainer'),
    toLoad = { 'images': [ 
       'http://myserver.com/image1.png', 
       'http://myserver.com/image2.png' ] }; // list of image URLs

toLoad.images.forEach(function(imageToLoad) {
      remoteImage = new RAL.RemoteImage(imageToLoad);
      container.appendChild(remoteImage.element);
      RAL.Queue.add(remoteImage);
});
RAL.Queue.setMaxConnections(4);
RAL.Queue.start();

Remember that you need permission in the manifest.json to all domains you will be XHR'ing to. If you don't know beforehand where those images will be hosted, you can ask permission for any url:

    permissions: ['<all_urls>'],

For other usages, please see the simple demo at: https://github.com/GoogleChrome/apps-resource-loader/tree/master/demo
