I would think $10 per image would be about right over the course of a year, say 2000 images online (across the top sites) should make $20,000 a year without too much stress (aslong as you're not just uploading your holiday pics) and I would say those who are researching and producing 'stocky' images would easily beat that, this is more about the longer term view than an instant money back at the end of the month.... I think gostwyck is right you have to put it into context.
