That might have been the 161st image taken by an old Sony camera.

Cyber-shot model names use a DSC prefix, which is an initialism for "Digital Still Camera".

The filename for sure comes from the camera. My point was that the crawler stopped there and did not pick up the other images on the page because all of them have a higher number in the name and it stopped at an artificial number of sub urls
