Why should you expect to find more images in the Snail-Po gallery than in the episode gallery? You know, the ones where Snail-Po appears.
Because it's a separate page where you're going to find more detail anyway?
You don't go to a subgallery for more detail on the subject, but instead to see all the images of the subject.
