Hello..
Sorry Staffs, but you are changing the thread, he didnt ask about SHOW AVATARS(FROM OTHER PEOPLE), and neither about changing avatar on the website, because I saw that it doesnt have any relation with your own messenger, I have uptated my website avatar by about 4 weeks, and it is that "P" Palringo Logo, Every Palringo's user have it.
Not good, because you know he is asking about CHANGE AVATAR, change display picture on messenger/other services, and you talk about another things, and dont answer his question.
So, I wil answer, YOU CANT CHANGE IT!!! very bad thing, everybody that see you, know you are on the phone, using palringo, and not in home.
