I found an additional way for image blog webmasters making more money. The main income of a blog is from the ads on the site or from affiliate programs. But image blog webmasters can earn more money from your images. You can find it here. I'm using it on my blog and adult forum and the result is great.
You say images make money? I don't think so...There are millions pictures in the internet...And I treat them as rubbish...
