If already have a photo service, try looking for a "Forum" link, or just use the provided photo's URL in between IMG tags. If you don't have an account with Photobucket or Flickr try out <a href:"
http://tinypic.com/">TinyPic[/url]. You don't need an account to start. Just click off the popups, click on "Choose File" then "Upload Now" (you may have to do a Capcha). Select everything within the "IMG Code for Forums & Message Boards" box, and paste it here.
