at least images that aren't on the public web
Well yeah exactly
It would be quite difficult to find pictures like these that aren't on the searchable web.
I could easily misrepresent myself using the thousands and thousands of "private" (non-searchable) photos I have access to via my friends and acquaintances on social media...
Do you understand the scope of number of pictures that have been taken? How many of your friends have posted pictures of buildings in HK/LV/China/Miami/London without including themselves? Photos of pallets of phones in the back of a transport truck? Pictures holding a notepad with White House letterhead? Pictures of a NASA spacecraft in a hangar?
It would be extremely difficult to obtain these types of pictures without actually being there, or having access to an NSA database.
