DEMO: PicasaStore Search
</h1>
<hr>
<h3>
Description:
</h3>
<p>
This simple demo shows how services, such as Flickr, can be wrapped by the datastore API. In this demo, you can search public Flickr images through a simple FlickrStore by specifying a series of tags (separated by spaces) to search on. The results will be displayed below the search box.
</p>
<p>
For fun, search on the 3dny tag!
