I have seen a nice mod in this phpbb forum: http://www.vagito.net/help-with-photo-album-vt139.html
There for every new topic the second post is a advertisment that don't stress the users.

Search the boards and you'll find examples abound of how to do this.
Yes I know, but no one is like this one. No one of this for SMF seems like a normal user.
