I have a snippet: 

```
 $(document).ready(function(){
    $('.imgtlist').each(function(index) {
        $('#slide_box').attr('width', + 135);
    });
});

```

Essentialy, on load, count the number of nodes with class `.imgtlist` and add 135 to the width attribute of `#slide_box`.

Do I need to define a var for the each loop and then increase based on the number of `.imgtlist`?
