Where did you do this? After I login I only see My Details and that's it. Can you do some screen captures of the pages after you create a new account. Is it possible I am missing something.
Ah, I see your problem now. The link in your menu to "My Details" links to the Joomla user info. You need to delete that link and add a new component link to Community Builder. The default component link will take you to the user info page of the person that is logged in. That page looks like this:
When you put your mouse over "Edit" there are several options, one to edit your info, and one to upload an image.
