title: Facebook share button anchor tag vs including javascript
body: <p>What is different of having a facebook share button just by having an anchor tag:</p>
  
  <pre><code>&lt;a href="http://www.facebook.com/sharer.php?u=&lt;url to share&gt;&amp;t=&lt;title of content&gt;"&gt;
    &lt;img src="custom.jpg" /&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>than having one with the javascript provided by FB follow by the anchor tag? </p>
  
  <pre><code>&lt;script src="http://static.ak.fbcdn.net/connect.php/js/FB.Share" type="text/javascript"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>I just want to verify I'm not missing any of the basic functionality of sharing a link by using the anchor tag only because I want to use the anchor tag way to customize my button image.</p>
