Checked it out myself. As a negative, it was too steep for one picture (and honestly, I wouldn't post a unique pic here again.) As a positive, context clues are against the agency theory.
I think as long as it's on topic you're fine to post in the main thread. Like, sometimes when people post the teasers or free posts or whatever it's because they're just fishing for someone else to post the content, but you've posted enough stuff here already that it's not the case. If anything gets too out of hand with discussion we can always move it into a different thread later.
