I've come to this

    <% 0.upto(7) { |x| %>
      <div id="dragg<%= x %>" class="green box"
style="position:absolute;top:<%= 190+((x / 4)*195) %>px;left:<%= 55 + (x *
195) %>px"><div class="handler" id="handler<%= x %>">Imagen <%= x
%>&nbsp;<%= check_box_tag "cruzar"+x.to_s%></div><%= link_to_remote
image_tag("/generate/imagen/"+x.to_s), :url => {:action=> "generate", :id =>
x}, :update => "show_div" %></div>
      <%= draggable_element "dragg"+x.to_s, :handle => "'handler"+x.to_s+"'"
%>
    <% } %>

Someone out there might be needing this. :) Just be careful with the use of
<%= x %> and simply 'x' (without the quotes) or x.to_s
