The best printed photos have archival lifetimes estimated between 100-200 years for monochrome prints with Epson ultrachrome pigmented inks on archival papers or Giclee prints, nowhere near a million years.
That is true Joe, but if photos were never exposed to light and keep at a constant temp of some 3-4 meters underground surly we could expect a much longer period before any degrading.
I know a million is a fair stretch,  so maybe half million.
