Photo curation question: Where do the non-highlighted photos go?

Taking this taxon as an example, when you click on the main image, it will open a dialog where you can cycle through all of the chosen photos. These photos won’t necessarily be associated with a particular observation, though, since they can also come from external sources (such as Wikipedia). By contrast, clicking on “View More” will only show photos from observations, and they can be ordered either by faves or date added. So even if a taxon photo does come from an observation, there’s no guarantee that it will appear near the beginning of the “View More” list.
