How do you add quotes and/or pictures to your posts?

I don't know if this has already been covered, but almost everybody seems to have quotes and/or pictures under their posts. How do you set that up?

edit: sorry, I misunderstood your question.

It's as simple as changing your sig in the profile. Images and colors work there as in the posts. You just have to write the proper code. [img]image[/img], etc.
