Follow this link. JohnB has done a great job of explaining how to do it.
Basically, there are two different ways:
1) Go through the photo hosting thing under the Photos page of this site.
2) Go through an outside photo hosting site such as Photobucket or Webshots.
I use Photobucket because I started at that prior to the thing on here becoming available. I also think the one on here is a little more complicated than the outside ones. JMHO.
