Are you trying to post a link, or photos (neither shows up in your post)? If the former, post the link without the "http://" part, just in the main text. If the latter, hit the "go advanced" and do "Attach files" and "manage attachments." For the photos, you may need to post 9 more times, though there are a fair number of new members who are able to get photos up on their first few posts.

EDIT: And welcome to the forums!
