Neat simple little trivia thing, but fun to think about each one and any clues. I got 1969, 1968, 1971, 1906 and 1904, score of 3435. First two were war related, for 1000 and 777. First was b&w but obvious forest clearing mid Vietnam war, so bit of a guess but on the dot, then the second was a color picture of a bus with "Saigon" on it that I underestimated but again, era was clearly Vietnam. Second one showed people in front of cricket scoreboard and with all the batters names and that was pure luck for me because only one possible famous match featured those players! (test #679, Australia v Sydney 1971). Utterly bombed the next, 83 points, I agree with others that I found older photos tougher. Guess 1923, way off. Then I could guess at the final based on the period late 1800s/early 1900s dress at 1910 which was good for 575. Anyway, fun in terms of trying different strategies and it making one focus on the details whereas normally with photographs it's easy to just sort of look at it more abstractly without really thinking about it. Could be a neat party game even as-is, but I also agree with a sibling poster that it'd be easy to expand a touch to favor that (allow having n different guesses each with different colors, so everyone can take a shot for each image for some light competition maybe?).
