What does the flickr widget need to extract the thumbnail images from the feed? I'm trying to merge my flickr and smugmug RSS feeds using Yahoo! pipes. When I install the flickr widget in my local install of wordpress (2.1) the feed works fine. But using the same feed url in my wordpress.com widget shows either the More Photos link or it shows the titles of the images. But it never shows the thumbnails.
Here's my Yahoo! pipes feed: http://pipes.yahoo.com/pipes/pipe.run?_id=0LpT5tEc3BG4bhe8y6ky6g&_render=rss
The plugin I have installed locally is this one: http://donncha.wordpress.com/flickr-widget/
