Technically speaking, you don’t add a tracking pixel. You add a link to something the client loads. The server on the other side can send whatever he wants, even different things to different clients. And given that there have been vulnerabilities in image parsers more than I wish to remember, that may quite well be malware.
- bdamm 7y agoYou just defined a tracking pixel. Ok, technically it is larger than a pixel, but if the server with the image is harvesting information about the client to learn something about the user, then it's tracking the user.
