This is part of a RHTML file for showing all JPEG files as a list:

  <% bilder = Dir["*.jpeg"] %>
  <ul>
  <% bilder.sort.each do |bild| %>
  <li><a href="<%= bild %>" /><%= bild.chomp ".jpeg" %></a></li>
  <% end %>
  </ul>

This is part of a RHTML file for randomly show a picture from a
picture list like above:

  <% bilder = Dir["../*.jpeg"] %>
  <img src="<%=bilder[rand(bilder.length - 1)] %>" alt="" />
