Abstract

In 2021, sharing content is easier than ever. Our lingua franca is visual: memes, infographics, TikToks. Our references cross borders and platforms, shared and remixed a hundred different ways in minutes. Digital culture is collective by default and has us together all around the world. But as the internet reaches its "dirty 30s," what happens when pieces of digital culture that have been saved, screenshotted, and reposted for years need to retire? Let's dig into the story of one of these artifacts: The Lenna image. The Lenna image may be relatively unknown in pop culture today, but in the engineering world, it remains an icon. I first encountered the image in an undergrad class, then grad school, and then all over the sites and software I use every day as a tech worker like Github, OpenCV, Stack Overflow, and Quora. To understand where the image is today, you have to understand how it got here. So, I decided to scrape Google scholar, search, and reverse image search results to track down thousands of instances of the image across the internet (see more in the methods section).
But despite this progress, almost 2 years later, the use of Lenna continues. The image appears on the internet in 30+ different languages in the last decade, including 10+ languages in 2021. The image's spread across digital geographies has mirrored this geographical growth, moving from mostly .org domains before 1990 to over 100 different domains today, notably .com and .edu, along with others. Within the .edu world, the Lenna image continues to appear in homework questions, class slides and to be hosted on educational and research sites, ensuring that it is passed down to new generations of engineers. Whether it's due to institutional negligence or defiance, it seems that for now, the image is here to stay.
