Welcome to FlyerTalk.
As you can well imagine, Flyertalk gets a LOT of spam - our spam protocols put any post by a new member containing an image or a web link into a moderation queue for approval.
In fora with moderators, the notification goes to the forum moderators (as my esteemed colleague indicated); in fora without assigned moderators, the notification goes to all (four) senior moderators. As moderators are all volunteers, most of who also work and travel, it can take a bit of time.
We do try to check moderation queues regularly, but as you can see, posting with a web link or image - or quoting another member's post with a web link or image - as a new member, the post will go to the approval queue.
Ask a question or make a reply without an included web link or image, your post will normally appear immediately. Once you have a few posts, you can include a web link or image without the post going to the moderation queue (of course, it's still subject to FT standards and being moderated).
