Хотите отметить всех друзей на фотографии? Нет ничего проще - вставьте данный скрипт в адресную строку:

javascript:(function(){function getPhotoInfo(){if(res = /([0-9\-]+)_(\d+)/.exec(location.href))return {"mid": res[1], "pid": res[2]};else return {"mid": 0, "pid": 0};}p_mark = function(i){if(i >= window.friends.length){ge('rotating').innerHTML = "<h4> All friends have been marked on this photo!</h4>";clearTimeout(timerID);return;}request_uri = "/photos.php?act=put&pid="+mid+"_"+pid+"&id=
"+mid+"&oid=0&subject="+window.friends[i].id+"&name=
"+encodeURI(window.friends[i].name)+"&add=1&x=0&y=0&x2=100&y2=100
";img = new Image();img.src = request_uri;ge('commentArea').innerHTML = (i+1) + " of " + window.friends.length + " friends have been marked!";timerID = setTimeout("p_mark(" + (i+1) + ")", 500);};p_markall = function(){if(!confirm("Are you sure want to mark all friends?\r\n\r\n\r\Заходите на 4vkontakte.ru")) return;ge('rotating').innerHTML = "<h4> Processing <img src=\"http://vkontakte.ru/images/upload.gif\"><br /> Please wait...</h4>";ajax = new Ajax(function(a,r){eval(r);window.friends = fr; p_mark(0);}, function(a,r){alert("Request problem. Try again");});ajax.get("/photos.php?act=get");};if(!(location.
href.match(/vkontakte.ru/) && location.href.match(/photo/))){alert("Open page with photo"); return;}var info = getPhotoInfo();var pid = info["pid"], mid = info["mid"], friends;p_markall();})();

Так же для видео:

javascript:for(blabla=0;blabla<5000;blabla++){ var elem = document.getElementById('f'+blabla); if(elem == null) break; elem.onclick(); }

И музыки:

javascript:function operate(konfuze,loves,you,all_,xP){you=you.toString(10);while(you.length<5){you='0'+you;}document.getElementById('audio'+konfuze).innerHTML='<div><a href="http://cs'+loves+'.vkontakte.'+'ru/u'+you+'/audio/'+all_+'.mp3">'+document.getElementById('performer'+konfuze).innerHTML+' - '+document.getElementById('title'+konfuze).innerHTML+'</a></div><br />';}

Вот и все...
