You can override the confirm method to temporarily silence it and return true. Below example will silence a confirm dialog only once, and only if it's called. Once the silenced dialog is executed, it will restore its original functionality and subsequent call to confirm method will work as normal.

var realConfirm=window.confirm;
window.confirm=function(){
  window.confirm=realConfirm;
  return true;
};
click(picture element);
