You should use a for loop. To iterate on every element matching your array-like object of elements returned by getElementsByClassName .

window.onload = function yourFunction(){
    var elements = document.getElementsByClassName('icon');
    if (elements){
      for (var i = 0; i<elements.length; i++){
        elements[i].innerHTML = elements[i].innerHTML.replace(/_s.png/g, ".png");
      }
    }
    setTimeout(yourFunction, 5000);
}

yourFunction();
