This Pipe produces a feed of your Flickr photos posted to a tag you specify. However, it strips out the text "So-and-so posted a photo." The point here was to be able to post Flickr photos to Twitter, so I wanted the text as compact as possible.
I have no idea how to translate between your Flickr ID, your Flickr display name, and the username in a Flickr URL, so unfortunately you have to enter all three.
