I've got a JSON structure like this and want to refer to the 64x64 image in a dust template. This doesn't work because of the 64x64.

```
   "images": [
        {
            "dateLastUpdated": "2014-02-24T23:00:00Z",
            "links": {
                "1024x1024": "http://imghost/some.JPG",
                "147x147": "http://imghost/some.JPG",
                "358x358": "http://imghost/some.JPG",
                "498x498": "http://imghost/some.JPG",
                "64x64": "http://imghost/some.JPG",
                "726x726": "http://imghost/some.JPG"
            },
            "status": "OK"
        }
    ],

```

This is the dust.js template

```
{#users}
<tr>
  <td><img class="thumb" src="{.images[0].links['64x64']}"/></td>
  <td>{.title}</td>
</tr>
{/users}

```

I've tried 

```
{.images[0].links.64x64}
{.images[0].links['64x64']}
{.images[0].links.'64x64'}
{'.images[0].links.64x64'}

```

How do I do this?

**Update 1**

I've found a workaround which solves this specific problem but not the general one. If I would want to refer to different sizes in the loop I would have the same problem again. 

```
{#users $size="64x64"}
<tr>
  <td><img class="thumb" src="{.images[0].links[$size]}"/></td>
  <td>{.title}</td>
</tr>
{/users}

```

**Update 2** 

Should have mentioned the dust.js template in the question :)
