Use html elements inside your survey (type:'html')

Source code: Survey setup
Survey.defaultBootstrapCss.navigationButton = "btn btn-primary";
Survey.Survey.cssType = "bootstrap";
var survey = new Survey.Model({ questions: [
    { type: "html", name: "info", html:"<table><body><row><td><img src='http://surveyjs.org/images/26178-20160417.jpg' width='100px' /></td><td style='padding:20px'>You may put here any html code. For example images, <b>text</b> or <a href='http://surveyjs.org/builder/index.html'  target='_blank'>links</a></td></row></body></table>" }
]});

function onAngularComponentInit() {
    Survey.SurveyNG.render("surveyElement", {model:survey});
}
var HelloApp =
    ng.core
        .Component({
            selector: 'ng-app',
            template: '<div id="surveyContainer" class="survey-container contentcontainer codecontainer">' +
            '<div id="surveyElement"></div></div>'
        })
        .Class({
            constructor: function() {
            },
            ngOnInit: function() {
                onAngularComponentInit();
            }
        });
document.addEventListener('DOMContentLoaded', function() {
    ng.platformBrowserDynamic.bootstrap(HelloApp);
});

html property:

var q = survey.getQuestionByName('info');
q.html = yourHtml; 
survey.render();
