/*

Using the previous example, you can store the final Open XML snippet in a data attribute (e.g. data-base64) using jQuery

   $this.data('base64', data)

and if you want to get the data again, use the following code:

   $this.data('base64')

Where $this is a localised pointer to the image tag in jQuery. This code usually runs from a click event. 

*/

if (!$this.hasClass('local')) {
    //do what we did before (but remember to apply the local css class once it's finished...
} else {
	    //previously clicked on the image
    	Office.context.document.setSelectedDataAsync(
			imageOXmlTemplate.replace(
				'{Base64}',
				$this.data('base64')
			),
			{ coercionType: "ooxml" },
			function (asyncResult) {
				if (asyncResult.status == "failed") {
								//Again. Do something!
				} else {
					$this.removeClass('busy');
				}
			});
