Widget:FlickrUserH2
Using this widget
This widget was written by Steve Rainwater to replace the now deprecated Flickr badges that showed a Flickr user's most recent photos.
To add a horizontal flickr stream badge to your profile, drop in this code, replaced the user ID with your Flickr User ID. You can find your Flickr ID by going to flickr home page and looking for small orange RSS "subscribe" icon on the lower left. Look for "id=" in the URL it links to and copy everything between the '=' to '&' :
{{#widget:FlickrUserH|user=8386148@N06}}
