I am all but certain that this is the DOM purify routine that is stripping out the html. There is a way to configure the tags so that it will accept IMG within the renderer. Something like this may work.

Formio.createForm(document.getElementById('formio'), '.....', {
  sanitizeConfig: {
    addTags: ['img']
  }
});
