Retro PC? How about ASCII printouts (not on-screen as the 80 column 25 rows black-n-white (actually dark green and light green) screens weren't enough even with our high school freshman imagination) off USSR clone of IBM/360 in the 198x - couple meters long at something like 200 characters per row, and had to be viewed from a distance of like 3 meters to see the picture instead of just rows of ASCII ... Running and collecting the printout from the University datacenter so that the typical operator there - a young woman - wouldn't catch you was a Mission Impossible endeavor on itself.
For the original question - i think we humans had always been making it possible using whatever tech is available at the time, for example i think that is "nude pictures" too https://en.wikipedia.org/wiki/Venus_figurine
