The "mistaken" screencap that appeared in Q3436 has the filename: DnKZP5pUcAA6hx0.jpg
That is a twitter image filename, and this same image seems to have appeared on twitter on 9/15/18, the same day that Q posted "Q 2174"

It seems Q got the Q post cap from that twitter account.
The attached two images are the ones I just got from that account. Is the cap exactly the same?
The fact that going to the link shows you "see Q" is probably a good thing....
This article might have been somehow picked up from QR, since the top pic there with Pinker,etc was in a notable last week.
After seeing the notable I archived all the Billionaire Dinner pages and posted links there. The only one missing was 2000, but here is an archive page from cache link in the article. The image that is blocked is just a rotating display of the other images.
Of note is that Nathan Myhrvold is shown there talking to Epstein. Dershowitz claims that Virginia Roberts confused him with Myhrvold.
(don't have sauce at the moment....)
