50,000 photos aren't that hard to amass if you're old. Digital photography was available to enthusiasts in 1998. If you took ~200 photos a month, you'd have 52,800 (200×12×22).

(I've personally got several times that: it's why I wrote PhotoStructure)

Undoubtedly true. I have 10,000 song files with the same problem!
