Fully agree. I'm the creator of the website but AFAIK, it is not easy to get the license to use images. If anyone knows more about that topic, please let me know!

Good point. As of now, we only tested it with STU3. I think something we definitely miss is a test module that allows for version compatibility checks.

I'll be watching this project. I hope you can keep advancing it. Maybe put a note on the README about version compatibility and a call to action for testing new versions as they come out?
