This is not the jjb-you cannot post pics directly on here-you have to post the link. How do you do that you ask?
When you click the "add reply" button or the button to start a new thread you'll see a series of buttons like B I U
FONT etc... right above the text box you're typing in. Click on the button labeled "http://" then enter the URL to the pic you want to post and press "ok". Next they'll ask you to name the link. You can just put the word pic or whatever you want then press ok again. It'll automatically post a link where you can click on to see the pic.
Hope that helped
