How Do You Center An Image In Your Signature?

[Limon]

I'm probably just dumb and can't find where to do it when it's probably in my face.But I've been really curious.It annoys me seeing the gif on the left side. I'd like to place it in the center.I hope I posted this in the right General Discussion.Any help?
