Javascript-форум - Эффект "фотоальбом"

Помогите, пожалуйста, советом.
Во всех браузерах эффект работает нормально,кроме"Opera".Не сказать,что вообще не работает,но работает с большими перебоями.Появляется "фотоальбом" редко и только, если множество раз обновляешь ту страницу,на которой он находится.Какая проблема может быть в скрипте?
