I've made a tool for making "Which One Doesn't Belong?" pictures.
You can put text or pictures in each square, and change the colours of the  background and text.

I've updated my #wodb maker to prompt for image descriptions, and to show you suggested alt text for the final image. 
Suggestions for a better format for the alt text are welcome!
