New and needs help

[Tales-of-Sharingan]

Hi guys^^
I'm just arrived here...
and I'd like to know a thing...
I dunno why but...
if I link my profile to some friends (not registred on this hosting) they cannot see anything...but if I link them one of my picture they can see them...
only my album and my profile are not showed...
why?
have I did any mistakes?
I've tryed to read all term of service but...i'm not english so...maybe I've misunderstood something
