I've been looking at some of these sites recently for inspiration for a new project, and I see that you can upload photos and images and get commission when someone downloads one. I was just idly wondering if this could be a good way of making a bit of extra money, or if there are so many millions of images on the sites that it's unlikely you'll make anything?
If you have some of your work on any of these sites, is it worth it? What are the most popular types of images? What are the best image sites to use? Any other tips?
Thankyou!
