How can I return a list of page assets with Paperclipped?

I tried to do this, but the app kept complaining about a missing “title”
attribute:

<r:assets:each>
<r:assets:asset_file_name />
</r:assets:each>

I need to render a list of all images attached to a page. How can I do
this
with Paperclipped. I thought Paperclipped superseded page_attachments? I
like the way it manages assets, but getting to them is not always as
easy as
page_attachments.
