Bob - you can't upload pictures to this site, you have to link to them. Your pictures have to be uploaded to somewhere on the web (e.g., flicker, dropbox, etc.) and then link to them. To reference a link, you click the image icon while posting () to inject an html tag, then edit the address of the link that was provided by the upload site (i.e., http://flicker.com/myalbum/mypic.gif).
