I think it is a great thing. I have some photos on a German Website, where they had it now a longer time. I sold one Photo twice and that was all together arround 45 Dollar! On dt,ss and fotolia I got for that not more than 3 $. But my other photos have not sold except for two on this German site. I am really happy about ss, because they have a fixed price and 20$ sounds really good. Lets see how that will work out. Do you have any information about Dreamstime, I thought I heard something about an extended license, but when I searched through the message board I could not find anything..
