Firstly, you’ll need to upload your iworkontheweb profile onto flickr.
Secondly, tag your flickr photo with the machine tag "iworkontheweb:name=My Name" (don't forget to include the double quotes). See the machine tags on Lisa’s flickr photo for an example.
Thirdly, wait around five minutes (or a bit more if Flickr is feeling tired) and find yourself magically added to iworkontheweb.com.
Make sure your Hiding from Search Flickr account preferences does not hide your photos from 3rd party sites, and that your account has been reviewed as safe and NOT NIPSA (top paragraph of your account page).
See Flickr's Content filters FAQ page for more information.
Simply remove the "iworkontheweb:name=" machine tag from your photograph, and in five or so minutes it will have been removed.
