hey killnu,
To post pics you first have to upload them to a server. You ISP may have given you space for a personal web page, or you could use some of those free picture posting sites. Once you get it uploaded and can view it in a browser, right click on the picture and choose properties. One of the properties will be the URL, or address for where the picture is stored at. Then on the message board here, you click on the"IMG" button above the "reply" field and put the address in there, and voila ! you posted a picture!
