> https : / / upload.wikimedia.org / wikipedia / commons / e / e3 / Pen_Register.jpg ? utm_source=commons.wikimedia.org & utm_campaign=index & utm_content=original I was nerd-sniped by the above link (which I've added spaces to, to keep it from being truncated) and thought "Huh, since when does Wikimedia Commons use tracker barf?" So I found the page for this image: https://commons.wikimedia.org/wiki/File:Pen_Register.jpg https://commons.wikimedia.org/wiki/File:Pen_Register.jpg then copied the full-size image's link... and sure enough. I guess they want to keep tabs on sites that hotlink their images and don't even practice good link hygiene.
