This is possible because Lemmy doesn't proxy external images but instead loads them directly. While not all that bad, this could be used for Spy pixels by nefarious posters and commenters.

Note, that the only thing that I willingly log is the "hit count" visible in the image, and I have no intention to misuse the data.

It appears to have worked

The user-agent detection definitely isn't great, this was just meant as a quick proof of concept for anyone curios.

A picture in a comment?

You could also send the image through a DM if you want to find a particular user

I've also started working on my own Lemmy app (in NativeScript). Maybe we should all create a community to share insights.

The user-agent detection definitely isn’t great. If it doesn't recognize a client, it just says unknown. But that wasn't the main point of the post anyway, this was just meant as a quick proof of concept for anyone curious.

Thought about adding the user's location, but was worried PythonAnywhere could somehow cache the image between multiple people. A great demo though!

It's just a simple Flask server. I parse the user-agent using the user_agents Python library, apply some conditionals upon the result, render the image using Pillow and send it to the user.

That's weird. The extension should definitely work with the image, as that's what I used when building this quick demo. Does the content of a site like this update?

It does

Yeah, I just use whatever the user_agents Python library gives me as user_agent.os.family.

If you wanted to target a specific user, you could always send a DM with the image

Oh, how did I not notice that before? Now should be fixed.

Yup, I'm parsing the user agent with the user_agents Python library.
