    document.getElementById("htmlContentArea").className = "unhidden";
    
    shareOperation.data.getHtmlFormatAsync().then(function (html) {

            var htmlFragment = Windows.ApplicationModel.DataTransfer.HtmlFormatHelper.getStaticFragment(htmlFormat);

            // Set the innerHTML of the ifram to the HTML fragment.
            var iFrame = document.getElementById("htmlContent");
            iFrame.style.display = "";
            iFrame.contentDocument.documentElement.innerHTML = htmlFragment;

    // Loop through any images and use the resourceMap to map each image element's src.
    var images = iFrame.contentDocument.documentElement.getElementsByTagName("img");
    if (images.length > 0) {
        shareOperation.data.getResourceMapAsync().done(function (resourceMap) {

                    if (streamReference) {
                        // Call a helper function to map the image element's src to a corresponding blob URL generated from the streamReference
