title: Disable link_to tag in Rails3+
body: <p>I used the following code:</p>
  
  <pre><code>&lt;%= link_to image_tag("edit.png", :alt =&gt; "Edit"), edit_user_path(user) %&gt;
  </code></pre>
  
  <p>I want to disable this link and image, so I added <code>:disabled=&gt;true</code> to the code, but it's not disabling. Why not, and how do I disable them?</p>
