title: prettyPhoto gallery without rel attribute
body: <p>I'm using prettyPhoto (<a href="http://www.no-margin-for-errors.com/projects/prettyphoto-jquery-lightbox-clone/" rel="nofollow">http://www.no-margin-for-errors.com/projects/prettyphoto-jquery-lightbox-clone/</a>) </p>
  
  <p>According to documentation it's being triggered by:</p>
  
  <pre><code>$("a[rel^='prettyPhoto']").prettyPhoto();
  </code></pre>
  
  <p>However, I'm using just this (rel attribute is not valid according to W3C and it's not needed):</p>
  
  <pre><code>$(".photo a").prettyPhoto();
  </code></pre>
  
  <p>But I need to make my photos as a gallery, according to documentation it's made by using this:</p>
  
  <pre><code>&lt;a href="images/1.jpg" rel="prettyPhoto[pp_gal]"&gt;&lt;img src="images/1b.jpg" /&gt;&lt;/a&gt;
  </code></pre>
  
  <p>(rel tag has gallery name between <code>[</code> <code>]</code>)</p>
  
  <hr>
  
  <p>Is there any way how to define gallery without rel tag?</p>
