New in v1.3

• 🖼️
  Doubles found by the picture itself, not the name
  The same photo saved with another name, in another size (like a WhatsApp or Telegram copy) or as a PNG is found by looking at the picture. A different photo with the same name is never called a double. The biggest, best copy is kept; click another one to keep that instead. Turn it off with "Same picture check".
• ⚡
  Still very fast
  Each picture is read as a tiny preview, many at once, and remembered for next time.

Also in v1.2
