这是我的最终解决方案，考虑了不同的浏览器

            "var body = document.getElementsByTagName('body')[0];" +
            "var insertionPoint = body.lastChild;" +
            "body.insertBefore(headerElement, insertionPoint);" +

            "var headerElement = document.createElement('div');" +
            "headerElement.innerHTML = '<img src=\"URLTOSOURCE" />';" +
            "var body = document.getElementsByTagName('body')[0];" +
            "var insertionPoint = body.children[0]; " +
            "var unityPlayer = document.getElementById('unityPlayerEmbed');" + 
            "unityPlayer.parentNode.insertBefore(headerElement, unityPlayer.nextSibling);" +
            "var embedTag = unityPlayer.getElementsByTagName('embed');" + 
            "embedTag[0].setAttribute('style','display:block;width:1200px;height:600px');" +

            "};";

    Application.ExternalEval(injection);

string injection=“if（navigator.userAgent.indexOf（\'Firefox\”）>=0{+
“var headerElement=document.createElement（'div'）；”+
“headerElement.innerHTML=”+
“var body=document.getElementsByTagName（'body'）[0]；”+
