There's been a lot of furore about this (which was, admittedly, easy to never hear about), but the important is this:
Lena herself has asked that people stop using her nude modeling photograph (yes, that's what it's a crop of) and just let the image live in the past where it belongs.
See https://en.wikipedia.org/wiki/Lenna#Criticism / https://www.sfgate.com/news/article/How-a-Nude-Playboy-Photo-Became-a-Fixture-14878319.php for some more details, but the lena image has no place in computer graphics anymore. There are plenty of better images to pick from. In this case, a https://placekitten.com image would work just as well, if not better.
