An unfortunate side effect of the forum migration was that we lost some of the profile pictures. This is a particular issue because it makes your profile and preferences menu invisible! (You are supposed to be able to click on your photo). You can click on the black space at the upper right of the screen and it will reveal the menu. Choose preferences and you can upload a new picture.
You can also get to the preferences from https://forum.openrov.com/users/<your_user_name>/preferences
