Stock Images In Use
But of course it would be much more fun, when there are people, who like our work. Who enjoy seeing our work, like we like to create it. Actually I started to think, that I like to see others creative work, but I love more to see their creative process, how they mold and shape their work - I love live music, I love to work together with other photographers, I love to see the painter painting. But that's already another topic.
Finding your images in not very easy task, but not impossible also. There are several options how to find and locate your images, like Google Search, Bing Search, Google Books, Amazon, TinEye. The search is easier, if you have an unique username.
I made some searches and gathered screenshots of pages and publications with my images into Facebook page collection. You can have a look at them here: My Images In Use Collection
Lots of images of course don't end up on webpages or any electronic media. They are used on paper and prints. So I could never find all of them, but some I did.
1. If you are about to start stock photography, reconsider your username. If it's too common, ask support to change it. With unique name, you have less trouble to find your images.
2. Google with your username & agency name and your full name & agency name.
3. With TinEye, if you are using Internet Explorer or Firefox, install Tineye Plugin
