Adambillet, You have to put the picture up onto a hosted web space somewhere - we can't see a floppy disk sitting in your A: drive here on the other side of the planet. It has to be put on something starting with "http://", there is web space available for members, take a look under Announcements and that should give you the info you need.
You need to have a closing "[/img.]" tag after the file name (no "."), with no spaces between the tags and your name eg [img.]http://www.mywebspace.com/xxx/yyy.gif[/img.] (I put the "." in so the server didn't try to interpret this is a real image link).
Good luck selling the bike mate!
