>On photos, I’m not sure what I’d do with 200,000 photos. I have 7,623 which span 4 generations and 125 years at the moment.
Some of them might be historically interesting enough to preserve on Wikimedia Commons, for example if they depict places that look very different today, or stuff that you don't see in everyday life anymore.
That’s quite possible. I have around 150 historical photos i.e. over 100 years old which depict family life in Switzerland in the 1800s. I will look into that. Thanks for the suggestion.
