I need a contentbox like the following for my blog

<div id="content">

<div class="content_box_small">
<p><b class="green">flickr</b></p>
<div class="flickr"><script type="text/javascript" src="http://www.flickr.com/badge_code_v2.gne?show_name=1&amp;count=5&amp;display=random&amp;size=s&amp;layout=x&amp;source=user&amp;user=casparclaasen%40N00&amp;set=72157594227721918&amp;"></script></div>

Need some assistance. What are the details that the code uses? How can i create a similar one? Is it possible to edit this and add my photo feed, or i'd have to generate a whole new box?
