I made this tool when I was writing about an issue I had with my DIY weather station's anemometer PCB. I wanted a way to visually compare the PCB and thermal camera images and toggle between them to see where the overheating components were. So I thought I could quickly vibe code or "prompt engineer" a simple image comparison tool to do that(so I don't guarantee code quality or that it's without bugs).
