I have re-thought the fifo.nl avatar system a bit, because people were requesting either an option for self-hosted images or otherwise manageable. I have come up with the following solution:

1. check gravatar for a user-manageable avatar
2. else fall back to the fifo avatar system:
   1. check for a local avatar
   2. else check if there is a URL to redirect to
   3. or else display the "unknown" avatar

 If you set up a gravatar URL, claim your fifo userid so you can benefit from this, or ask me to set your email address for you.
