It works fine for me. The link after the picture has three components. One link to your Flickr account, where the picture is located. That hyperlink has your Flickr username on it. A second link takes you to Foter.com, where the picture is displayed. A third link takes you to the license explanation. Are you sure you’re not looking at the link the wrong way?
I’ve been using this a while in my blog, and I’ve even had several people thank me for promoting their pictures.
