That looks like eRb or Ruby on Rails or something but couldn't you just do:

<% @photos.each_with_index do |photo, i| %>
<a href="/photos/show/<%=photo.id%>"><img 
src="/photos/thumb/<%=photo.id%>"/></a>
<% if (i % 4).zero? %>
<br>
<% end %>
<%end%>

To get each_with_index you must require 'enumerator' but you could do 
Array#each_index and then instead of photo.id you have photos[i].id.  Of 
course, this all assumes that photos is an array.
