<h3>Carousel with dynamic content loading via Ajax from the Flickr API</h3>
|

<p>
|

The data is loaded dynamically from the <a href="http://flickr.com/services/api/">Flickr API</a>
|
||
|
|
method <a href="http://flickr.com/services/api/flickr.photos.getRecent.html">flickr.photos.getRecent</a>.
|
||
|
|
All items not in the visible range are removed from the list to keep the list small.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Note: There are constantly added new photos at flickr, so you possibly get different photos at certain positions.
