How Can I update my Avatar?

This question is related to this forum, Many people in this forum have avatar uploaded on their profile. I want to do so help me if you know where can I find settings to update my avatar.

You have to change Avatar in your ts client, your Avatar takes over the forum here.

I logged into myteamspeak account and still couldn’t resolve it.

What if someone uses different account for forum and Teamspeak client?
