Hi!
I made a litte plugin that shows the latest comments from your Flickr account in your blog's Sidebar.
As an added bonus it tries to automatically detect if you've got FAlbum (Flickr gallery integration for Wordpress) installed and offers to link the comments to your blogs gallery rather than back to Flickr.
The plugin can be downloaded at: http://blog.no-panic.at/projects/flickrss
Please provide feedback, so I can improve it!
cheers,
Flo
