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

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.

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

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

It does

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?

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

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

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

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.
