For information - the Technical and General fora display your boat's photo, since they are visible outside of the members' area. For the moment, I have put the JRA logo into your profile, in the "boat's photo" field, to demonstrate this, but of course it can easily be changed to something else of your choosing.
All the other fora, within the members' area, display your personal photo.
[Webmaster edit: Thanks for helping Georg, David. I've inserted your advice on the Help page.]
