I am not defending the use of Lena nor advocating for its continued use. A similarly useful replacement should probably contain similar types and degrees of detail so that image algorithms can be tested. The hair, skin, fabric etc. in Lena readily surface an algorithm's compression and convolution artifacts. The Lena image was chosen in part for its technical properties. Unlike the Utah Teapot also used for computer imaging, the Lena image is socially and academically inappropriate. Though suitable replacements can be found or made, most images are not suitable technical replacements. Doing so will probably be non-trivial due to the volume of existing technical decisions based on the Lena image. https://www.tandfonline.com/doi/full/10.1080/09500340.2016.1270881 https://www.tandfonline.com/doi/full/10.1080/09500340.2016.1...
