title: Correct PrettyPhoto rel attribute?
body: <p>Which one of these attributes is correct?</p>
  
  <pre><code>rel="prettyPhoto[gallery]"
  </code></pre>
  
  <p>or</p>
  
  <pre><code>rel="prettyPhoto[pp_gal]"
  </code></pre>
  
  <p>Is this gallery/pp_gal declared somewhere? Can i pass any image gallery to prettyPhoto dynamically (by executing an SQL statement to get some img sources, and pass them somehow to my link that triggers prettyPhoto)?</p>
