If this board supports custom fields I also suggest considering these services
fg-site
flickr
picasa
imageshark
...?
I can provide 16x16 icons
The board supports whatever I want to program

Not bad ideas but I don't feel we need to support a list of urls yet. Most people have a single personal website, blog or image hosting site as their 'primary' place. A member already has the capability to store a link to their primary website in their profile. So for now, we'll just move ahead with Facebook.
Thank you for the feedback!
