Sending Pictures Source From HTML palettezone to be dragged into myDiagram

Hello Everyone,

I would like to make a put images from HTML on the palettezone then the user can drag and drop it inside myDiagram, So the user has the variety of many images and he can drag and drop any of them. here is part of the code

// *********************************************************
// Second, set up a GoJS Diagram
// *********************************************************

var $ = go.GraphObject.make;  // for conciseness in defining templates

myDiagram = $(go.Diagram, "myDiagram",  // create a Diagram for the DIV HTML element
              {
                initialContentAlignment: go.Spot.Center,
                "undoManager.isEnabled": true
              });  // center the content
window.PIXELRATIO = myDiagram.computePixelRatio(); // constant needed to determine mouse coordinates on the canvas

// define a simple Node template
myDiagram.nodeTemplate =
  $(go.Node, "Auto",
    { locationSpot: go.Spot.Center },
    new go.Binding('location'),
    $(go.Picture,
        // the picture has a red background, only visible when there is no source set
        // or when the image is partially transparent
        {  margin: 10, width: 30, height: 30, background: "red" },
        // Picture.source is data bound to the "source" attribute of model data:
        new go.Binding("source"),
    $(go.TextBlock,
      { margin: 3, font: "bold 16px sans-serif", width: 140, textAlign: 'center' },
      // TextBlock.text is bound to Node.data.key
      new go.Binding("text"))
  );

// but use the default Link template, by not setting Diagram.linkTemplate

// create the model data that will be represented by Nodes and Links
myDiagram.model = new go.GraphLinksModel(
[
  { text: "Alpha", source: "https://lh3.ggpht.com/kuskOgZvjr5tefLkXUqGxt3wxFy1IUIqHEowuZfi8a6Qd9XeASiXulDDMhcq1yKGGII=w300" },
