object HTMLImageElement showing instead of image


I created an array of 2 images and tried to display them, but instead of the images I got the text:
object HTMLImageElement

I am sure my images are in the right directory which I am currently working with.

< template is="auto-binding">
   <section flex horizontal wrap layout>

    <template repeat="{{item in items}}">
      <my-panel>{{item}}</my-panel>
    </template>

</section>

  <script>
  (function() {
    addEventListener('polymer-ready', function() {
        var createImage = function(src, title) {
              var img   = new Image();
              img.src   = src;
              img.alt   = title;
              img.title = title;
              return img; 
            };


    var items = [];

    items.push(createImage("images/photos/1.jpeg", "title1"));
    items.push(createImage("images/photos/2.jpeg", "title2"));

    CoreStyle.g.items = items;

      addEventListener('template-bound', function(e) {
        e.target.g = CoreStyle.g;
        e.target.items = items;
      });
    });

  })();
  </script>

What am I missing here?


Solution

  • The easiest and safest way to do this is to put the img in the template and bind the src and title attributes like this:

    <template repeat="{{item in items}}">
      <my-panel><img src="{{item.src}}" alt="{{item.title}}" title="{{item.title}}"></my-panel>
    </template>
    

    Then createImage looks like this

    var createImage = function(src, title) {
      return {src: src, title: title};
    }
