I told you about Photos & Storytelling on the previous subpage and it is essential to the total impression and usability of photos.
If you also can shoote a photo which includes more than the observed it is a fantastic feeling to discover Pictures in photos, both while you are shooting and afterwards looking through your shots;)
Personally I best like these kinds of photos rather than the photos arwarded, because often the photographer arranged the constallation in awarded photos.
See a few of my Pictures in photos below.
Pictures in pictures
While creating pictures sometimes there will be more to see than the picture you thought of while creating it and that I find especially interesting like all the photos above;) I also use it on my page Cave Graphics where you find a short video as well.
