Method to allow multi-site users to post affiliates

I’m developing a multi-site using Blogs MU. One of the client requests is that each user (who will all have Blogs MU installed and have their own sub-domain) have a page on which they can easily put up picture links to their own affliates.

The users need to be able to easily add/remove these picture links.

I’ve looked at some different gallery plug-ins as a possible solution.

Are there any WPMU Dev plug-ins that could help me achieve this?
