I suspect the OP means the Avatar image to the left of most users posts.
Aside from the likely restriction on newbies to vie other users profile information; you also have to be logged in when trying to view it even if you have exceeded the likely 20 post restricted.
The bigger question would be why do you need to look at another users profile, there is very little in the profile that is public even when you can access it. Most information is in the profile signature which is displayed in the posts.
