Yea would love to post a anime photo or even one of me on here as my avatar. If you know how please fill me in.

To post a image just put the URL of the image between these two tags. [img]direct image link here[/img]

And to get a picture for your avatar, well first the image must be 90x90 or less.
Go to user control panel. Then go to profile. Then go to edit avatar and upload the image from your computer.
