Question: I have an `.each()` function that measures the width of each of the images within the class of `.item`. I need all the widths to be measured and then added to a variable. The variable then needs to be passed out of the function. This function below is only half done, I just dont know how to finish it off.

Any help much appreciated.

```
$('.item img').each(function () {

    var i = $(this).width();

});

$('.overview').css('width', i);

```

Answer: 
```
var i = 0;

$('.item img').each(function () {

    i = i + $(this).width();

});

$('.overview').css('width', i);

```
```
var i = 0;

$('.item img').each(function () {
    i += $(this).width();
});

$('.overview').css('width', i);

```
