Currently, the only User that knows about name/profile_url/image_url is the local robot. If the programmer wants to know any of this information about other robots, then it could be looked up (via reading the robot json profile). This info could then be cached, so that asking for name would also load the urls since most of the time none of this data will be needed, but if it is needed it is likely that all of the profile data items will be used.
Should also be possible for reading human information, but I have no idea where the profile is stored for non-robots.
