I know that feeling. It's good you still have data.
Curious why your processed images are gone, but not your originals.
Years ago I sent my PC off for a rebuild and the bloke wiped everything. Years of my bushwalk/ wilderness photos gone.
For many years whenever I transferred images from my SD card to my PC, I have alays duplicated them on an external drive (norm,ally switched off to extend its life). I have also done the same with with most of my software. I also keep a encrypted record of passwords, registration codes etc on the cloud!
However, I have been careless about my processed images (1 or 2 per day).
Here is today's one and only, nothing special, processed image.
Now I come to think of it, a large proportion of my processed images are stored omn the POTN sever.
