title: Get JSON object by attribute
body: <p>Say I have this JSON object:</p>
  
  <pre><code>var images = {"success":"true", "images":[
       {"id":"1234","url":"asdf","tags":["cookie","chocolate"]},
       {"id":"5678","url":"qwer","tags":["pie","pumpkin"]}
  ]};
  </code></pre>
  
  <p>What would be the most efficient way to get the url of the image with an id of 5678? Can use jQuery.</p>
