Initially I felt a bit lost. There were so many different options available and I wasn't sure where to start. First of all, I realized that even though I had taken hundreds of photos over the years, I had to ask myself this question: What kind of photos actually sell online?

I tried to put myself into the shoes of someone who buys photos online. That includes magazines, web design companies, publishing companies and advertising agencies. These companies or publications are looking for photos of high quality and resolution to illustrate a product, service or idea.

Over the course of a few days I went through my photo collection and found quite a few suitable photos that showed different objects, travel landscapes, animals and trees. But I quickly realized that even though I had figured out how to sell photos online, I first had to improve some of my photos in Photoshop.

After establishing an account with several stock photo agencies such as Shutterstock, Fotolia and Dreamstime, I finally started to sell my photos online. I uploaded a good part of my improved photo collection and since that point I've been earning money each time one of my photos was downloaded by a buyer. Of course, not all of my photos were accepted by the stock photo agencies, but many of them were.

I told all my friends how to sell photos online and they were very excited. You too can take advantage of this opportunity and sell your photos online. You don't have to go with an online stock agency; you can charge more money per photo if you set up your own website store to sell your photos. But on the other hand, finding a buyer for your photos would be more difficult because you won't attract the same kind of traffic as an established stock photo agency does.
