Hey there man. Looks like you have the avatar figured out. As for pics, there are a couple ways you can do that, you can either upload them to the gallery here (just click on the "Gallery" link at the top of the page and follow the steps) or you can do what I do and start a free account with a site like Photobucket. You just upload your pics to that site and then all you have to do is copy/paste the IMG code directly into your posts. That's the easiest way to do it.
