If you mean a YouTube button, then use this code:
- Code: Select all
[youtube=30,25]INSERT LINK HERE[/youtube]
It'll only show the 'Play' button.
If that's not what you mean, then I can't help, I'm afraid.
Wait, oh! You mean the avatar?
Click the little box with your account name, then Settings. Click Profile Setup, and the first field should be 'Change Picture'. From there, choose a picture on your computer you want, or a still from your vid.
