Every time you stick a camera card into a card reader, the Photos app will auto-launch asking to import it. That can be a royal PITA, and Apple has not provided a way to turn that off. And each time that card gets erased, recorded to, and put back into the card reader, Photos thinks it is a brand new card it has never seen.

This simple App allows you to disable and re-enable Photos automatically launching when an SD card or other type of image media is mounted.
