I'm using this script to load small or large images depending on the screen width. 

```
    <script>
var jt_width = screen.width;
//var jt_height = screen.height;
if (jt_width < 361) {document.write('<div class="small-image"><img src="http://www.example.com/small-image.jpg" alt="small image alt"></div>') } else { document.write('<div class="large-image"><img src="http://www.example.com/large-image.jpg" alt="large image alt"></div>')};
</script>

```

The disadvantage is that on a mobile phone it doesn't change on the fly when someone goes from portrait to landscape, and I want to use jquery to do this.

I read online about different possibilities like using window.outerWidth or .width() and I understood that .width() is the best solution in terms of browser compatibility.

I would like to convert the script above to a jquery version, but since I hardly know anything about javascript I don't know how to do this. This is what I have

```
function load(){
    w.value = $(window).width();
    h.value = $(window).height();
}

```

How can I get the same output using jquery?
