It's not always clear how meaningful something will be at first glance. Most people had no interest in buying Vincent Van Gogh's paintings when he was alive, but enough people eventually saw them for the masterworks they were that even one can easily fetch millions of dollars at auction nowadays.
Although most of the images we're about to see today probably won't feature that stark of a contrast, they're probably not going to mean as much without a little context sprinkled in.
