<%= attachment_container @album, :files, newAttachments: { class: 'thumbnails' }, loadedAttachments: { class: 'span3' } %>
```

or use a custom layout:

``` html
<%= attachment_container @album, :photos do %>

  <a class="pickAttachments btn" href="javascript://">select files</a>
  <a class="uploadAttachments btn" href="javascript://">upload files</a>

  <ul class="loadedAttachments">
    <%= render :partial => 'photos', :collection => @album.photos, :as => 'photo' %>
  </ul>
