T put a picture up on the page, you go to New Thread, then scroll down past the box where you type all text, and you will see a button that says Manage Attachments, click it, and another box will come up. You click the Browse button, and pick the picture you want from your hard drive.

If you have a ad blocker or pop up blocker, you need to shut it off so that Browser box comes up, or you won't be able to post.
