title: jQuery select first image src in container with image filename extension
body: <p>This current code doesn't work.</p>
  
  <p><code>$loaded_data.find('img').match(/\.(jpg|png|gif)/i).first().attr('src')</code></p>
  
  <p>It will allow <code>img</code> with the ext of <code>.php?image=qweqweqwe2qe2ad</code> etc.</p>
