flickr_eyecandy is a very simple WordPress Plugin.
It provides a WordPress Widget that selects and displays one random photo from Flickr 
in the sidebar, each time the page loads. The plugin uses the Flickr API, and authenticates via 
an API key that YOU (the installer) acquire via the Yahoo API Console.
It does not present a gallery. It’s just one photo. The photo changes when you reload the page, but it does not change while the page is being displayed.
You specify a tag or set of tags to filter the photos. 
For example, if you specify “usa,flag”, you will get only photos tagged 
with “usa” and “flag”.
<h3>Dependencies</h3>
<ul>
<li>This plugin depends on and uses the published Flickr REST API.</li>
<li>It also relies on and uses the Curl library within PHP.</li>
<li>It makes outbound http connections from the WordPress/PHP server. Most hosters allow this, so it won’t be a problem.</li>
</ul>
<h3>Thanks</h3>
Thanks for your interest!
