As a user and contributor of stock, I have my favorites. If I had to pick only one for both, it would be
Dreamstime. As a seller, I like that they are one of the fairest sites for microstock contributing artists. As a buyer, they have fair prices and a decent website with the features I use. I have used other sites and have my favorites for this or that; but if I had to pick only one it would be
Dreamstime.
Who do you use and why?
