Subject: Rails view template for a gallery

I am totally new to rails, so sorry for the trivial question!

I have an object, gallery, that contains a list of images.  I want to
display these images in a table with 4 columns and as many rows as it
takes, closing the final table row at the end.

What is the best way todo this?

I can do it (mostly, the final table row is still left open) using the
following template, but it seems a bit hackish in places:

<html>
  <body>
    <h1><%= @gallery.name -%></h1>
    <table>
    <%
      i = 1
      for img in @gallery.images
    -%>
      <%= if i == 1 || (i-1)%4 == 0
            "<tr>"
          else
             ""
          end -%>
      <td><img src='<%= img -%>'></td>
      <%= "</tr>" if i%4 == 0 -%>
      <%= i += 1
          "" -%>
    <% end -%>
    </table>
  </body>
</html>

Is there a better way?
