In the following code, when the user clicks on the `'.more'` span element, I want to retrieve information (eg, the ID) from the `img` within the `article` tag using jQuery.

Here's the HTML:

```
<article>
<img src="..." id="TR"/>
<div>some text <a>link</a> <span class="more">read more</span></div>
</article>

```

I've tried this code: 

```
   $('.more').click(function () {

        var id = $(this).siblings().siblings('img').attr('id');

});

```

but it doesn't seem to work. Any thoughts?

Many thanks!
