Use sanitize. In your DB, the image-field is like , and when you try to "display" it in your view, rails still give you the url. What you can do is to use sanitize
Ex.
<% @entry.each do |t|%>
<h3><%= link_to t.title, t.url %></h3>
<p><%= t.published %></p>
<p><%= sanitize t.summary %></p>
<% end %>
This will give a thumbs-up to rails and "display" the "code" as a actual image.
