Both this toolbar and the contributor toolbar, along with picNiche.com are built and run with the purpose of gathering more data/information about what images buyers would like/need to purchase. I want to try and make finding those images, and supplying those images, as quick and easy as possible for both buyers and contributors.
Information about saturated and undersupplied markets is important to contributors, we'd all like to stop wasting time producing great quality work, which will never sell, and we'd very much like to be creating the work that image-buyers really really need.
Freelance software development and Microstock, is my full-time job. I love making images, but sadly, I have bills to pay, and I'm a much better software engineer than I am a photographer (for now ;).
Therefore the development of this toolbar and the costs of future maintenance and improvements is supported by the affiliate programs of agencies searched by the toolbars.
If you sign up to a new agency and purchase or sell images as a direct result of using these toolbars (using the buttons/tools to access that site), the agencies involved pay a small commission through their normal referral/affiliate programs to me. Thanks to you, and to the agencies :)
