There are some sites where you can host your images and companies (e.g. newspapers, magazines, but also 'normal' companies) can look at the photos and buy them. Some people earn good money doing that. There was an article about these sites once in a Dutch photography magazine, I'll look for it.............................
Found it, it was, of course, almost at the bottom of the (big) pile. There are some links:
Shutter Stock (for the Dutch)
iStock Photo
Dreams Time
Fotolia
Big Stock Photo
Stock Xpert
123rf
For many sites (maybe even all of them) you have to pay a certain amount of money per image, but you can earn nice cash too. I don't know how it works with rights though, whether you'll have the rights of the image, or the stocking site. If your image gets published, you'd like to see Toby Wilkins with it, not the name of some stocking site. This is probably something to look into.
