<h1>Find Photos on Flickr</h1>
<div class="exampleIntro">
<p>This example uses AutoComplete to find images by tag from the Flickr webservice. A simple PHP proxy is used to access the remote server via XHR. The <code>generateRequest()</code> method has been customized in order send additional required parameters to the Flickr application. The <code>formatResult()</code> method has been customized in order to display images in the results container, and the default CSS has been enhanced so the results container can scroll. Finally, a <code>itemSelectEvent</code> handler has been defined to collect selected images in a separate container.
