The Tink clipart is just fine. If you just want your name to appear around the clipart in your signature, just type it in before or after the clipart code and see what you get. We can help you fine tune it after you place it.
As far as "the picture over to the left of the post under the "author" " is concerned, we call those "Avatars". You can add them through your "Options" screen in your user control panel. We can help out with this as well if you need it.
