Google Image Search

The trick is to know what words will be on a page with interesting images. School photos are one place to start. If you want French schoolboys from 1964, you could plug in "cm2 1964 garçons site:.fr". "Cm2" is the French equivalent of 5th grade. There will be plenty of places to explore. You could narrow things down by specifying a minimum picture size, so you won't get buried under a bunch of postage-stamp-sized images. Anyway, you'll wind up on sites like http://sigoise.free.fr/spip/spip.php?article137, with images like this. When exploring French sites, a lot of the hits will be on sites nostalgically remembering the good old days when French Imperialism hadn't yet collapsed, mostly from North Africa. If it's German images you're interested in, "klassenfoto 1964" is one place to start. That might take you some place like http://picasaweb.google.com/116431388089875456994/KlassenfotoSteckborn. That turns out to be Swiss, and not German, but why be picky? There's a trick to get full-sized images at Picasaweb - when you open an image like: http://lh3.ggpht.com/-GxviLbBEBXQ/SIIDHDnExuI/AAAAAAAANtg/txkT2v7fMvw/s912/Scannen0337.jpg, edit out the "/s912" size limit to get to the maximum-sized version: http://lh3.ggpht.com/-GxviLbBEBXQ/SIIDHDnExuI/AAAAAAAANtg/txkT2v7fMvw/Scannen0337.jpg. Google Translate can be useful for finding terms in different languages, such as school, class and so on, but you also need to look over the interesting pages you find to see if there are other terms that seem likely to be important. Is there anything specific you had in mind?
