Thank you everyone for your feedback. It's helped me the Flickr Shortcode Importer beyond what I had originally intended into something that's now more than a one-time usage tool.
With the help from Ĺ˝eljko of http://www.touristplayground.com/, I've pushed up header image at http://wordpress.org/extend/plugins/flickr-shortcode-importer/. We're really looking good.
While there, can you please give the plugin a rating and a works or not vote for the latest edition?
