It's not so clear that she doesn't want people to use that image. She has assisted several times at image processing conferences, and has stated recently that she was proud of the fact that so many people used that photo. The documentary linked above shows footage of herself talking about the photo, but she never really says people should not use it. The website hosting the documentary has several heavily editorialized quotations that suggest that. That said, this new "lennart" is hilarious and I would like to use it instead of the original one. EDIT: here's a 2019 interview where she appears to pose with the same hat again : https://www.wired.com/story/finding-lena-the-patron-saint-of-jpegs/ https://www.wired.com/story/finding-lena-the-patron-saint-of...
