I had half a dozen sales early on but nothing since. However they still pay me to upload and I just got my 2nd payout because of it so I will continue.
the top couple of images were used for testing so have high downloads. About 4-6 weeks ago I ordered all by sales and looked at how much had sales got to around page 15 with everything still having sales before I got bored
They have a recent sales thing with the last few sales. I hit refresh after about 15 minutes and it was a different 3 images, and it is different everytime I go there so they are getting sales but I think it is slow. Hopefully they will do some marketing soon, maybe I am just being too optimistic
