I haven't tried to figure it out myself, but if I had to take a guess, it's probably either the first page you edit for the day (24-hour period to be exact), or the last page. If all else fails, you can just make a comment on the auto-post pointing out what you've changed, or make a standalone post with that info.
By examining my recent update, it seems that the biggest screenshot belongs to the last page that has been newly marked as "edited" in the 24-hour period. For example, if I make a change to cool.html, then make a change to sick.html, then a change to neat.html, then another change to cool.html, it'll be neat.html that appears the largest. Hopefully this helps.
