Another method that I don't use, but I thought someone who is struggling might want to try it. Here's the story: met up with a friend yesterday who runs a very successful bookstore business. He imports/exports/distributes, etc. Anyway...one thing he is doing now, on the side for fun, is to access the National Archives (google it), find historical photos, pay $10 to have them pulled by people who work there, and another $13 to get a high-res scan emailed to him. Next, he uses his photoshop skills to touch them up, bring out shadows, add color, etc, then he uploads them to a photography retail site (tons of these--i'm not in this niche, so I have no idea which is best), and gets paid when someone orders his prints. The archives have thousands of photos in the public domain, and if you hit upon an area with a loyal following (early native american, great depression, jfk presidency, wall street, national monuments, national parks, etc), I'd think there could be a nice stream of passive income involved. Perhaps someone here can think of ways to tweak this, but I thought it would be worth sharing. You could do this no matter what country you live in, or you could visit your own national archives and share it with people in other countries. Places like Japan, UK, Germany, France, Belgium, etc should have some rich WW2 imagery, for instance!
